My sever is a dual core intel box, dedicated running CentOS and 1 gig
of ram. No other websites are hosted on this box
I have MySQL query cache of about 100M, which is being used quite a
bit when I check the cache hits
The php code is just HTML with inline php statements like, probably
about 75-100 lines
(this is just an example, my page uses CSS not tables)
<table>
<tr>
<td><? echo $someVar; ?></td>
</tr>
</table>
To check the execution time I use a fucntion as follows
function getmicrotime(){
list($usec, $sec) = explode(" ",microtime());
return ((float)$usec + (float)$sec);
}
I record the start time, and end time, then print the delta
Any other suggestions would be appreciated, thank you!
