comment Cannot increase MTU on gigabit network
@Sirex: 20% under what circumstances? @work I just measured 940 Mb/s using iperf without jumbo frames, which is 94% of the theoretical maximum, so a 20% improvement is just impossible in that case. (CPU usage was 5% of one core on the sender and 1% on the receiver; not only CPU's but also NIC's and the network stack in OS'es are different from 10 years ago.)

Or just forget about jumbo frames; it's not like they make much difference with current CPU's @1Gb.

comment What can cause kernel out_of_memory error?
He's using the RHEL5 kernel which has a lot of patches on top of vanilla 2.6.18, and gets security updates from the vendor. That being said, 2.6.18-164.9.1 is old and has several more or less serious vulnerabilities (newest EL5 kernel ATM being 2.6.18-194.26.1).

comment Accessing file on XFS partition over NFS locks up application
@pehrs: That's not the relevant choice, though. In reality, it's "lose data and don't get any indication which writes failed" vs. "wait until the server comes back online, or explicitly kill the app (with intr), or reboot the client"

@pehr: Yeah, well, soft mounts are quite convenient, at least until you lose data. ;-)

+1 ssh command keys or scponly/rssh is the correct approach.
