Will more CPU’s = faster RAW process time?

I work on Fashion shoots in NYC.
And regardless of the OS ( Mac or PC) it takes forever to process RAW files. (About 1500+ shoots a day)

Will Dual or Quad CPU systems {Win2k or Win2k3 OS} (U320 RAID 0 disks) decrease the time it takes to process these files or is it the nature of the beast?

What part of the system needs the most tweaking to get the best/fastest performace?

Currently use:
P4 3.0 GHZ/4 gigs PC2100/Wink2k SRV OS/P.S. CS/ATI 9800
U320 dual ch RAID 0 {2×18 & 2×36}
Files saved to File server (via 1GHZ switch) /U320 (8×72) RAID 0,5 burned to DVD.

The first thing to look at is the software that does the conversion. If it isn’t written to take advantage of a multiple processor system, all you can do is create multiple instances of PS. In addition, the usual suspects (RAM speed, Disk speed, Cpu speed, etc.).

Yes, ACR uses multiple CPUs.

More RAM and a fast CPU bus will also help.

Another thought is do you save the processed RAWs directly to an area on the fileserver?

If so, try comparing a smaller run against saving the processed RAW’s on your workstation. If you’re saving files across a network (even gigabit ethernet) then it may not be as fast as your SCSI RAID controllers can handle data. If you generate say 50MB TIFF files this may have an impact. If you’re able to process the RAW’s and save locally then batch copy to your server later for archiving.

If you HAVE to save over a network, ask your IT guys about a technology called EtherChannel which is available on Cisco network switches. It allows you to use multiple network cards in a machine and spread the load across them. This can be cheaper and easier than going to a higher speed network which can be very expensive. I’m pretty sure Windows server OS’s will support this feature.
