USB....Perfomance
Tweaking USB Performance

I've been tweaking my system lately, trying to get better USB performance. As a benchmark, I've been trying to burn a large file ( Win98 cab file of 180mb) on a new HP USB cdrom burner model 8200. Until now I was never able to finish the burn without a crash. I finally was successful....Here's the setup:

V2, winchip2, 64mb ram, 210mhz SoftFSB.

Win98se.

VIA 4-in-1 driver 4.25a.

VIA USB filter driver.

MemTurbo2.0 (set to automatically recover 20mb when memory drops to 6mb)

CacheMaster (set to cd writer setting)

I think cachemaster did the trick...It's a free program available here: http://www.nonags.com/nonags/ I am now running three things off a Belkin 7-port USB hub. Phillips USB speakers, a Logitech cordless USB mouse, the HP USB cdrom. I can now play mp3s perfectly, no drop-outs, off the USB cdrom to the USB speakers (never could before). Still experimenting with this setup......haven't tried the USB wireless LAN yet.......More to come.

Cachemaster is a very interesting program. Doing a complete test of it's capabilities is going to be time-consuming because of the many variables. And I'm certain results will vary, depending on your own hardware/software configuration. For me, using the setup in the above post, the results of some setting changes have been dramatic. I started out using it's cdrom writing ability as a benchmark....that doesn't work very well. The "cd writer" setting burns cds ok, but slows the rest of the system. I'm now trying the "multi-media" setting, which dramatically affected the speed of the rest of the system. I'm not sure what to use as a benchmark to test these different settings. Sandra hasn't been much help.

One thing you will find useful is the resource monitor guages. You can accurately monitor system resources (six different guages) while you are doing different things...playing mp3s for instance....and can then see what the setting changes are doing to your system performance. There isn't any one figure you can use, so your overall impression of a particular setting will have to be based on a seat-of-the-pants feeling.

I'm very impressed with this program...the different settings have a dramatic affect on the whole system.....getting the right setting for your particular setup will take some time. I'm interested in any results anyone might have. Try it......
