Vcache

[Wotan]

'MinFileCache' and 'MaxFileCache' should be the same : about 25% of your RAM,  to avoid resizing.

so on the system I am werking on has 384 ram so

should 1 set it

MinFileCache= 96000
MaxFileCache= 96000.........?

would this be correct.....?

seems high and if I understand it then the RAM used by vcache can't be used by applications.

with this setting what should chunk size be?

For 256 to 384Mb I multiply it all by 0.50
 
For over 384, I keep it at 384 x .25 x 1024 x .5 = 49152...
(which is getting pretty stinkin huge, no sense going any
larger no matter how much ram you have)
 
For the Min amount, just halve whatever the Max amount is.
 
Chunksize is always 512. (In fact, that's the default)


128 megs x 0.25 x 1024 =  32768 max
128 megs x 0.25 x 1024 x 0.75 = 24576 max
256 megs x 0.25 x 1024 x 0.75 = 49152 max
256 megs x 0.25 x 1024 x 0.50 =  32768 max
384 megs x 0.25 x 1024 x 0.50 =  49152 max
