1. I have played with hdparm ;-) So I know the UDMA mode of the servers. 2. Yes, it will be done next, but why should the onboard IDE on a "modern" AthlonXP board be much worse than an older IDE PCI controller? 3. Yes, right, but why is load so high with AFS on it? 4. The fileserver1 has OpenAFS, Apache2 and Subversion on it. And yes, the Apache2 is ONLY for subversion and yes, that are only 10 accounts in subversion, and while measure that speed, Apache2 was OFF. So "plain" OS and OpenAFS. Fileserver 2 was the same. 5. As for me being the only account on that machine, it was a ssh to that machine while that special move of a 2 GB file. I copied the file and tried with a second login to get some speed/load data with iftop and top, so I experienced the lag on SSH. And no, there are no other accounts on that machine.
6. to the other post: both machine were fresh rebootet and both are stucked with 1 GB RAM, I assume that to be enough. And both machine has 2 GHz AthlonXP. So I assume they are NOT swapping and I assume a 2 GHz CPU should be capable of sending 100 MBit out to the net.
OK, the database server is older and slower, but while moving one file between two fileservers, how much load is on the database server?
So at all, I�m kinda helpless for slowness of my network.
