<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Okay here is a quick breakdown of my situation; I have an
asterisk server with AMP installed. Amp stores all of the CDRS in a mysql
database and comes with a nifty web based reporting tool that has worked well
for me. The problem I am running into is that my mysql database is
nearing 2 million records, when we run any reports our CPU load spikes occasionally
causing us some issues with our PBX in general.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>The machine we run Asterisk on is a Dell 1850, 160 GB SCSI
drives in a mirror array, dual P4 3.06 ghz 2GIG Ram.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>I am currently reprogramming the msyql database to only
store 30 days worth of information and archive the rest. This will get
rid of the majority of our symptoms however the underlying problem is that the
mysql/php/httpd daemons can saturate the CPU and starve asterisk. So my question
is this, is “nice” aka CPU scheduling going to be a solution that I
will want to use or should I use CPU affinity and tie the processes to a
specific processor? Or would I be wiser to move the mysql database and
web server to another box?<o:p></o:p></span></font></p>
