Forum Server Load increased dramatically since I upgraded to vb4
 

Hello,
I was using vb 3.8.5 and upgraded to 4.0.3 yesterday.
Since then, the server load increasing dramatically time to time. Previously, they never go beyond 3 3 3 but,

At the time of post, its now "Load Averages: 261.59 232.69 136.43"

I have no mods installed except vbseo and vbseo sitemap generator. I have monitored the load by disabling all the plugins from config.php, but the situation remains same.

Where did I went wrong? What should I do to fix the issue?

Regards
Abhik
