The C3 is slow. I get it. I already *knew* that. However, the performance numbers I posted demonstrate pretty clearly that the failure is not in a simple lack of CPU power, but in truly how *much* CPU power rsync demands. I get triple the performance in switching from rsync to SMB. Same CPU, same network, same hard drives, different protocol. And interestingly enough, the load is far higher on the computer I'm backing up, not the poor little C3. It takes a 2.6GHz Xeon with SCSI RAID drives to force my anemic C3 to 100% utilization. I can live with that. So while my C3 is leaving *some* performance behind, it's nowhere near enough to cause me to switch from the tiny, attractive, quiet, reliable, affordable package I have develeped around the EPIA. (The DMA issue, though, might be. At least to a different motherboard.) The whole reason I got involved in this discussion is because others have repeatedly said that they get outstanding performance from cast-off machines. That may be true: but it wasn't true for me. I wanted to know why. And the reason is not the C3. It's rsync. Just to satisfy my own sick sense of curiosity, I will grab an extra NetVista I have laying around (1.6GHz P4) and see how much faster it runs. That might be a week or two. I'll let you know. Are there others out here using rsyncd? What type of performance do you get? Tim Massey ------------------------------------------------------------------------- Take Surveys. Earn Cash.
