What About Windows' Cache?

Responding to the current (and ongoing) discussion on virtual memory (the "swapfile") on the WinMag site, reader Victor Werbin wrote:

Virtual memory settings are only half of the puzzle. The Cache is the other (and in my mind, more important) setting to play with. As far as I'm concerned it is ridiculous that windows sucks up most of your memory to store files that it thinks you are going to use and then when you actually need memory it starts swapping stuff to disk to free up memory that would have been there waiting for you if it hadn't stolen it in the first place.

Limiting the cache did far more to increase my performance than setting a permanent swapfile did. I don't know where you change this setting in Win98, but in 95 it is done in the sys.ini file.

I can't remember my rational for using the settings that I used, but here is what my entry in sys.ini looks like:

[vcache]
MinFileCache=512
MaxFileCache=6144

I notice that at the 98lite site on this page http://www.98lite.net/perform.html  under the second chart they show that a normal tweaking for them includes a vcache min and max of 4096.

Maybe you have discussed this issue before, if not I think you might investigate and come up with some recommendations. Keep up the good work. I've gotten some great info from you. Thanks, Victor

Indeed, there may be something to this; Microsoft acknowledges that the Windows cache gets bogged down after long periods of file activity. (See http://support.microsoft.com/support/kb/articles/Q238/5/48.ASP; thanks to WinMag guru Dave Methvin for pointing this out.) So, in theory, changing the cache size should limit the amount of "paging" (swapping out chunks, or "pages" of memory).

But on the other hand, Microsoft also says this:

Changing the cache size is not a good method of limiting paging. Paging through the cache would quickly overwhelm it and make it useless for other file I/O. Although swap file I/O operations do not go through the cache, memory-mapped files and executable files do. The cache, however, is designed to make sure it cannot be overwhelmed by such I/O operations.

Changing the cache size (even if you could) probably would not have much effect on paging. The cache grows and shrinks as needed. If the system begins to page a lot, the cache shrinks automatically. However, people often think they are seeing a lot of paging, but they are really seeing other disk activity, such as Windows 98 building its icon cache or the cache lazy writing.

So, which is right--- Microsoft's "wouldn't have much effect" or the anecdotal evidence of some users that manually setting the cache sizes does help? I'm trying some of the new settings myself using an automated freeware tool, and I hope some of you will do so, too. Either way, join in the very active discussion area at http://content.techweb.com/winmag//columns/fred/1999/0913.htm and share your results; I'll be posting mine on Monday!

Something That *Will* Definitely Help Speed Windows

WinAlign and MapCache are Microsoft tools "designed to optimize the performance of executable code (binaries) on the Windows 98 platform." WinAlign works by adjusting your EXE files so they're stored on disk in a way that mimics how they'll be stored in RAM, when you run them. (Many EXEs are shipped pre-aligned, but this tool can take care of the rest). Once the EXEs are aligned, MapCache (which runs automatically as part of Win98) then can operate at top efficiency.

If you have the full $70 Win98 Resource Kit, you already have a copy of WinAlign and all the supporting information you need to use it.

For everyone else, Windows Magazine offers a free tool called WMalign that can do much the same thing as WinAlign, except it won't cost you $70. <g>

You'll find full info, a download, and instructions---all for free--- here: http://content.techweb.com/winmag//library/1999/0301/fea0052a.htm

What About WordPerfect?

Commenting on my recent coverage of the free-for-the-download StarOffice from Sun (see http://www.informationweek.com/langaletter) a reader asked "Fred why the hell haven't you (and by extension, your colleagues) shown the same enthusiasm towards WP?"

StarOffice has been around for years. I had little enthusiasm for it in the past because, beyond personal evaluation copies, it was an expensive commercial product offered by a small company of uncertain solidity. It's hard to recommend a pricey product with an uncertain future unless that product is clearly light-years ahead of the product it's trying to replace. StarOffice comes close to being a tier-one suite; it's not as good as MS Office, but it's free, and it's now backed by Sun. Those two new facts make a huge difference: because SO is free and backed by a major company, one can look past the hassles of conversion and the product's imperfections.

WordPerfect costs a couple hundred bucks and is from a company with an uncertain future. In fact, WP's own future has been decidedly uncertain ever since the Novell days. As I said, it's hard to recommend a pricey product with an uncertain future unless that product is clearly light-years ahead of the product it's trying to replace. WP is a decent office suite, but it's not light years ahead of anything.

If WP were picked up by, say, IBM or Apple and offered for free, or even if Corel offered it for free, that would be different. But as long as it costs a couple hundred bucks and is from a company with an uncertain future, I'm hard-pressed to commend it.

But your mileage may vary. Come add your voice to the ongoing discussion at http://www.informationweek.com/langaletter !

Update on the "Java Update"

Several issues ago, I told you about a potentially major security hole in Microsoft's Java implementation. (See http://www.langa.com/newsletters/Sept-2-99.htm#bug1 )

Microsoft initially issued a full-blown (6MB) replacement for the entire Java subsystem, and followed up with a much smaller Windows Update patch that simply altered your existing Java setup. 

Reader George Combos did some digging and found the following:

The 161 KB JVM patch on the WU site is version 3167. The 6 MB JVM update (full package) at http://www.microsoft.com/java/vm/dl_vm32.htm is version 3186.

When a Win98/98 SE user goes to WU (windowsupdate.microsoft.com) after upgrading with JVM 3186 full package, the ActiveX engine that searches the user's computer for installed updates shows only the JVM patch 3167 [161 KB] as uninstalled (critical upgrade).

Therefore I believe Win98/98 SE users need to install both, the JVM 3186 full set first, and only after that go to WU to get the small JVM 3167 patch. The 3167 patch is not available (yet) as a separate download from the MS JVM page, and Win95/IE5 users cannot install it. :(

Also, if a Win98/98 SE user goes to WU without having JVM 3186 (full) installed, it also shows this one as a critical upgrade.

Keep up the excellent work! Sincerely, George Gombos

Interesting, George! I'm not sure you'd need both---if you've added the full version, then adding the small patch probably wouldn't add any functionality. It might, however, stop the Update site from telling you you needed a "critical update."

Anyway, with the version numbers, now readers can see which version, if any, they've upgraded to. (Use the techniques described in http://www.langa.com/newsletters/Sept-2-99.htm#bug1 to get your Java VM version number.)

Sneaky DOS Shortcuts

Most Windows users know that the Desktop, Start Menu, and such are just ways of looking at standard directories on your hard drive. The complete contents of your Desktop are actually in \windows\desktop, for example. The complete contents of your Start Menu resides in \windows\start menu, and so on.

Because of this, you can use old-style DOS shortcuts to navigate around. For example, in DOS, typing a period (".") was a shorthand way of referring to the current directory. Two periods were a shortcut to the directory one level up from where you are; a backslash by itself ("\") represented the topmost directory; and so on.

You can use these shortcuts in the Start Menu's Run line. If you type a period in the Run line and click OK, you'll see an alternate view of your Desktop. Type two periods and click OK and you'll see the \windows directory, which is "one level up" from the Start menu. Or, type "\" (without the quotes) and you'll be at the top-level directory.

You also can use these DOS shortcuts in the Explorer's address bar. 

Try 'em--- you may save yourself some pointing and clicking!

Y2K-AOK!

Reader "Irene" tried the 5-step do-it-yourself Y2K test article I wrote about a while ago. (See http://content.techweb.com/winmag//library/1999/0101/fea0061.htm ) Her results may be interesting to anyone who hasn't tested their system yet:

Hey Fred:

Despite your warnings and encouragements, I procrastinated and delayed the task of peeking inside this mystery machine of mine to determine whether or not it was Y2K-Ok. Fear was a major deterrent -- fear of screwing up the computer and fear that I would find out that I was Y2K-NotOk.

Add to the mix the fact that just the thought of doing anything without the benefit of Windows caused me to age well beyond my years. I had thought BIOS were paragraphs in the back of a book that told you about the author.

That said - guess what? I did it. I finally decided to give it a go. I had read your pleadings for many months, so I went to the referenced WinMag page and followed the directions. I was terrified. My heart was pounding as the thought of my computer imploding was forefront in my mind.

I expect that the majority of your readers are more techno-savvy than I am and would scoff heartily at me. However, for those few who are in the same position, please continue to remind them and to let them know that if I can venture, albeit briefly, into the windowless world and return safely, then perhaps they could do it also.

Keep up the great work. Thanks, Irene

Glad it worked for you, Irene. The 5-step test is fast, free, and actually more accurate than some of the commercial Y2K-compliance tests I've seen. Plus, it doesn't try to sell you anything (the way many Y2K test suites do, using fear to make you want to update your hardware or software).

Y2K testing can be easy,  free, and take only a few minutes! With only 14 weeks to the Y2K deadline, if you haven't yet tested your system, you really ought to now. Check it out at http://content.techweb.com/winmag//library/1999/0101/fea0061.htm .

Just For Grins

George Tullius sends along this tune (sung to the melody of "Home on the Range"); the lyrics were attributed to one Peggy Ben-Fay Hu:

VERSE:
Oh give me a site where the links all work right --
one that doesn't take too long to load --
where the text can be seen on my 13-inch screen --
one that offers a "no-Java" mode.

REFRAIN:
Home, home on the Web, on my 486 IBM.
Please take pity on me -- I'm still on Netscape 3 with a 14.4-speed modem!

VERSE:
Though your video files give your pages some style
I can't read them upon my PC;
Massive graphics and sound crash my system, I've found,
so please put in some "alt" tags for me!

(REFRAIN)

VERSE:
Please don't ask me to "chat" with your favorite cat;
I don't have an IRC code. 
And don't ask me to buy games for Win 95 --
My PC is way too darn old!

(REFRAIN)
