I saw a substantial improvement in IMP by implementing the IonCube
PHP accelerator:
http://www.php-accelerator.co.uk/  on the IMP server.  It's simple to
install.

Also, check Apache tuning, Solaris tuning (use the script below to
list your ndd parameters) -- look at Sun's site for what to change
based on the results of ndd.sh.

Look to see if your database is using much CPU.  If it is, there are
probably slow queries that can be indexed.


<BEGIN SCRIPT>

#!/bin/ksh

# ndd.sh

PATH=/usr/sbin:$PATH
if [ -z "$1" ]; then
   echo "Usage: $0 [udp | tcp | ip | icmp | arp | ... ]"
   exit
fi

ndd /dev/$1 '?' | nawk -v c="ndd /dev/$1" '
/write/ {
  split($0,a,/[ \t(]/);
  n=c t " " a[1];
  printf "echo %s = ",a[1];
  printf "`%s`\n",n;


}' | sh
