title: MySQL 5.0 High CPU Usage - performance tuning
body: <p>Env: Webapp running on tomcat-6 with hibernate-3 as the interface to db.</p>
  
  <p>Since recently, MySQL has been hogging up 100% of CPU time.</p>
  
  <p>I am doing consecutive reads of a large number with little to no writing to DB.</p>
  
  <p>The service was setup with the default my.ini params. Unable to debug where the issue is arising out of.</p>
  
  <p>PS: I was reading about the leap second bug and thought it might be related because though MySQL is running on Win XP 32 bit, the windows OS itself is running on a linux OS as a VM image. Could there be an issue because of the leap second fix not being applied on the underlying linux?</p>
