Re: Increasing performance of PB5.0



Yes Michael, this RAID seems to be a good one.

FYI, I use AVG Free and am very satisfied with it: simple, efficient and not
very intrusive. I have a PB Workspace that Clean Builds a reasonably-sized
CEPC image (5.8 MB NK.BIN) in 11'45" with the AVG "shield" active. When I
disactivate this shield, it takes 10'05 instead. So the difference (100 s /
605 s = 16.5 %) is significant but endurable. My PC is a 2-years old Dell
Dimension 5100, Dual-core P4 @ 3 GHz, 1GB RAM, Maxtor 6L160MO (Serial ATA).

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

Keep in mind that with AV software, most of the time is spent checking that
executing files do not contain viruses. In the case of Platform Builder,
these files can be well known: batch and exe files in WINCEROOT but also exe
files in X:\Program Files\Windows CE Platform Builder and the mostly spawned
X:\WINDOWS\system32\cmd.exe.

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.

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?
