<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Hi
Guys,</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">This
one has me a little baffled.  If have a recent build (in the last week) of
FS installed on two near identical HP servers.  One happily runs 400
concurrent calls at around 50% CPU.  The other can only run around 50
calls without the CPU going to 98%.  Identical configs and lua script.</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Only
diff is that the server having problems is running latest centos 64bit, where
the other is 32bit.  Any suggestions of where I might start looking?</span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;"> </span></font></p>

<p><font face="Arial" size="2"><span style="font-size: 10pt; font-family: Arial;">Regards,</span></font></p>
