For whats it worth , I found my load average was higher when i<br>
switched over to mythbuntu 12.04 as well. For me it was the move from<br>
ext3 to ext4 on the OS partition with the mysql database, especially<br>
the write heavy recorded seek table. There are some mount options you<br>
can apply , but they are said to be risky in event of power failure.<br>
Barrier , commit interval , xattr and writeback.<br>
<br></blockquote><div><br>Thanks for that, I forgot back those ext4/mysql issues Migrated my mythbuntu install back to my software Raid partition with ext3 rather then ext4<br><br>Load averages are back to normal.<br><br>
