CentOS 4.4 e1000 and wire-speed
...g CentOS 4.4 on a Dell Poweredge 850 with an Intel
Pro/1000 Quad-port adapter.
I seem to be able to only achieve 80% utilization on the adapter, while
on the same box running Fedora Core 5 I was able to reach 99%
utilization.
I am using iSCSI Enterprise Target as my application and I am using the
nullio feature, it just discards any write and sends back random data
for any read, for my bandwidth test. The IO pattern I use is 1MB block
sequentials.
Is there something in the OS that is throttling the bandwidth as it
seems to be capped at 80%.
I have selinux and iptables disabled, and I have tuned...
