Hi good people,<br>Recently, I&#39;ve been charged with babysitting a HP ProLiant DL360 G3 server with 2 dual core Intel Xeon 3.06 processors and 2GB of RAM. The server runs MySQL and IIS. I have installed Spotlight on MySQL on my PC to monitor the server and it tells me that it has about 1.2GB free RAM. This figure has been consistent even when the server is under heavy use.<br>
<br>Now, my problem is that over the last few days, the processor usage has been averaging 90% which is very abnormal. In task manager, the top three processes in order of processor use are System Idle Process, w3wp.exe and mysqld-nt.exe. Even when processor use is above 90%, free RAM never goes below 1GB. What could be causing System Idle Process to use so much processor time yet its memory use is costant at 16k?<br>
<br>Another thing, the server has 2GB virtual memory. Is this too much/little considering the total RAM is 2GB? <a href="http://support.microsoft.com/kb/555223">This article</a> suggests that RAM should be 1.5 times the RAM, is this a must?<br>
<br>And finally, much as I would really like to, I cant replace the IIS and Windows with Apache and Linux. <br><br>Thanks.<br><br>Regards,<br>Peter.<br>
