The following tuning settings are common to all the tests in this study. Individual studies have additional configuration and tuning information.

Since the tests use multiple network interfaces, it is important to make sure that all the network interfaces are not going to the same core. Network interrupts were enabled on one strand and disabled on the remaining three strand of a core using the following script:
allpsr=`/usr/sbin/psrinfo | grep -v off-line | awk '{ print $1 }'` set $allpsr numpsr=$# while [ $numpsr -gt 0 ]; do shift numpsr=`expr $numpsr - 1` tmp=1 while [ $tmp -ne 4 ]; do /usr/sbin/psradm -i $1 shift numpsr=`expr $numpsr - 1` tmp=`expr $tmp + 1` done done |
The following example shows psrinfo output before running the script:
# psrinfo | more 0 on-line since 12/06/2006 14:28:34 1 on-line since 12/06/2006 14:28:35 2 on-line since 12/06/2006 14:28:35 3 on-line since 12/06/2006 14:28:35 4 on-line since 12/06/2006 14:28:35 5 on-line since 12/06/2006 14:28:35 ................. |
The following example shows psrinfo output after running the script:
0 on-line since 12/06/2006 14:28:34 1 no-intr since 12/07/2006 09:17:04 2 no-intr since 12/07/2006 09:17:04 3 no-intr since 12/07/2006 09:17:04 4 on-line since 12/06/2006 14:28:35 5 no-intr since 12/07/2006 09:17:04 ................. |
The following table shows the tuning settings used for the Proxy Server.

The tmpfs filesystem was used to carve a 4Gbytes filesystem out of memory. This tmpfs filesystem, which keeps all files in virtual memory, was used for caching purposes.
$ mkdir -p /proxycache $ mount -F tmpfs -o size=5120m swap /proxycache |
This creates a 5Gbytes filesystem in main memory. Although only 4Gbytes are actively used by the proxy server, a 5Gbytes filesystem provides some spare room.
