Re: Increasing performance of PB5.0

Raid Controller LSI MR-320-2E 128MB RAID PCI-E 8x.

Raid 0 with two disk of type HD SCSI U320 68p Fujitsu Alleg9 147G 10K.



I'm pretty sure that in my case the disk is not the bottle neck, because
there are not so much disk accesses during this 5 minutes of inactivity.

But I now temporarily disabled the Virus Checker and this improved the build
from over 15 minutes to about 9 minutes.

So I have to talk with our network administrator to disable the virus
checker for the windows ce folder on my PC.

Hi,

What on earth is it doing this 5 minutes?

Mostly file copies, but involving quite a lot of intermediary processes
each time a file of bunch of files is copied, e.g.
pbspawn.exe/cmd.exe/nmake.exe/cmd.exe/xcopy.exe.

As Vinz said, disks seems to be the key.
How is your RAID 0 done? How many disks in it? What kind of disks? What
stripe size?

Also, an unefficient antivirus software can cost you a significant amount
of time. Did you try to disable your Virus Checker just for a build? What
is the gain?
