Hello,
Have these issues started occuring since the database was reloaded from backup?
Here are a couple of documents which you could check out for the throughput issue:
* How to correct slow backup performance, slow virus or pre-job scans, and agent initialization problems on fragmented Windows NT, Windows 2000, and Windows 2003 server partitions

do the test notifications run fine?
Thanks!
