system.ini - what do you have under [vcache]??

system.ini - what do you have under vcache?

I have this
[vcache]
Chunksize=1024
MinFileCache=16384
MaxFileCache=16384

under virtual memory I have: 256min /256max

I have an IBM GXP75, 128 Megs of CAS 2 Infineon P3 700, ATI ALL IN WOnder Pro 32 Meg Card

DO my Vcache and virtual memory setting look ok?

I have the following :
[vcache]
MaxFileCache=57344
MinFileCache=32768
Chunksize=512
NameCache=4096
DirectoryCache=96

[386Enh]
MinPagingFileSize=262144
MaxPagingFileSize=262144
ConservativeSwapfileUsage=1

The idea is that i want things to hapen fast when i copy and install things. I've set the typical role of the machine to be 'network server' and have set relatively high values to the 'vcache' settings above. It is probably a bit of a memory waste, but i have 256 Mb pc-133 memory. By setting the ConservativeSwapfileUsage to 1, and the MaxFileCache i avoid the use of swap.

I have prompted serveral threads over this topic. I'm still searching for a resource that explains, in technical detail, the best way to determine optimal vcache and why. The information at ms.com is pretty vague about this setting, they explain what it does (basically the opposite of virtual memory), but don't discuss optimal settings. I have 512MB RAM and windows set it as follows:

minfilecache=16386
maxfilecache=131072
chunksize=512

Apparently windows determined that it should be 1/4 my system RAM. Yours is set to use 1/8 of system RAM. Did you set it or did windows? I also notice that your chunk size is twice mine. Have you added the ConservativeSwapFileUsage=1 statement in 386enh?

[386Enh]
ConservativeSwapFileUsage=1 //makes windows not always using SwapFile, only if RAM is full
PagingDrive=C: //I've got a Raid system using several Partitions this "C:"
has 550MB only for Bootingfiles and a 512MB SwapArea
MinPagingFileSize=524288
MaxPagingFileSize=524288

[vcache]
ChunkSize=128 //Best for Burnin'
MinFileCache=65536 // 1/4th of RAM
MaxFileCache=65536 // 1/4th of RAM

Looked at my son's Win98SE PC, the section under [vcache] has NO ENTRIES! His system has 256MB of ram, but windows left the vcache settings empty. I wonder why it left this section blank?

My dad's ME system also has NO [vcache] section in sys.ini.

Does anyone know how windows handles this situation or why it left these blank?

I ran a series of test with WinTune98 and found that with my system, WinME - 256meg ram, best performance came from letting Windows manage vcache (no settings in system.ini). On my system manual setting for vcache was best with the chunks at 512, min 2048, max 32768.

You can view my abbreviated test results at

But of course, use your own tests and judgement.

I've read where setting vcache manually was a good idea in Win95. Apparently Win98/Me/2k handles memory much better than 95 and manual tweaks really aren't necessary.

My win98se had nothing originally, I tried adding a few mentioned lines, found no visible difference to the eye, so removed them again.

 

[emjem]

Yep Dee67, all measurements that I made in WinTune98 were pretty much a wash re performance. The only measurable difference is shown in the table on the temporary web page I put up above -- and I don't think most users will be able to "see" the difference.

That table shows a few settings you should not use if you set it manually and want to FINE tune performance.
