Hi Jen,

W3WP process high CPU utilization can be related to many things in CRM Server. Please check following:

> How the CRM Organizations Dashboard are designed. Is there much data to load every time a Dashboard loads, if yes please recreate the dashboard to avoid much data load every time.

> When there is high CPU utilization for W3WP.exe please deactivate any Custom Plugin (if there is any) and see if the CPU utilization falls down immediately or not.

>Please make sure that other Application than CRM is not using the CRM AppPool.

> Please make sure you have sufficient Disk space in to your CRM Server

>Please see event viewer for any error message when this happen

>Please see for HIGH CPU and Memory utilization into the SQL server

>Please see which operation is performed by the users maximum at that time when you can see high CPU utilization by W3WP process

Ensure you are using 'using' statement around any connection.  I usually find high W3W is due to memory usage which is associated with connections being left open.
