I am posting this as an FYI. I burned a lot of time on digging for this solution. The problem was performance between newer AIX p series boxes and a sun 4500 with a fiber nic. I tried many misc. solutions but this turned out to fix the issue. My bandwidth benchmark went from around 20MB/sec to... (1 Reply)
I am running FC4:
Linux maincomp 2.6.13-1.1532_FC4smp
I recently changed the OS from windows XP, and have a feeling that for some reason my wireless network card is slower on Fedora Core 4. The Belkin PCI 802.11b card was automatically detected and configured by FC4 when I installed the OS,... (0 Replies)
About 4 years ago I wrote this tool inspired by Rob Urban's collect tool for DEC's Tru64 Unix. What makes this tool as different as collect was in its day is its ability to run at a low overhead and collect tons of stuff. I've expanded the general concept and even include data not available in... (0 Replies)
I have a Teradata Machine, using MP-RAS Unix, with a 1000 Intel Ethernet card and a Cisco switch.
If I configure the ethernet card and the switch to auto, so they negotiate to 1000, or configure the ethernet card and switch manually to 1000Full or 100Full, the velocity is very very low.

I have identical M5000 machines that are needing to transfer very large amounts of data between them. These are fully loaded machines, and I've already checked IO, memory usage, etc... I get poor network performance even when the machines are idle or copying via loopback. The 10 GB NICs are... (7 Replies)

PMDAKVM(1) Performance Co-Pilot PMDAKVM(1)NAME
pmdakvm - Linux virtualisation performance metrics domain agent (PMDA)
DESCRIPTION
pmdakvm is a Performance Metrics Domain Agent (PMDA) which exports metric values from the Linux KVM virtualisation subsystem.
Unlike many PMDAs it dynamically enumerates its metric hierarchy, based entirely on the contents of /sys/kernel/debug/kvm.
INSTALLATION
If you want access to the names and values for the kvm performance metrics, do the following as root:
# cd $PCP_PMDAS_DIR/kvm
# ./Install
If you want to undo the installation, do the following as root:
# cd $PCP_PMDAS_DIR/kvm
# ./Remove
pmdakvm is launched by pmcd(1) and should never be executed directly. The Install and Remove scripts notify pmcd(1) when the agent is
installed or removed.
FILES
$PCP_PMDAS_DIR/kvm/Install
installation script for the pmdakvm agent
$PCP_PMDAS_DIR/kvm/Remove
undo installation script for the pmdakvm agent
$PCP_LOG_DIR/pmcd/kvm.log
default log file for error messages from pmdakvm
