I'll be deploying a single processor (+HTT) HP DL-380 G3 with 6Gb RAM and two RAID 1 volumes. This uses (at least in 4.x) the bge network driver and the ciss SCSI driver. Is this even reasonable to consider right now or are they known to be completely untested? The current proxy supports over 500 users performing about 15 requests per second. This is hitting the limit of the IDE disk in the current machine. (systat -vmstat routinely shows the disk being 100% busy). To me it seems like a good way of exercising both the network and disk subsystems. I realise that I may be gambling here, but I am prepared to fall back to the old machine the time it takes to revert to 4.8 if I had to, but then I'd be limited to 4Gb, which would be a bit sad. Then again if 6Gb and/or the application isn't enough to contribute a useful datapoint then I'll probably specify the machine for 4Gb only and be done with it. Thanks for any clues I can use (especially "I have the exact same setup and it works fine" :) David Landgren
