Performance problem

After a disk failure ( disk was in raid 1 configuration ) SQL Server
start to work very slow.
SqlServer start to raise following event
Event Type: Information
Event Source: MSSQLSERVER
Event Category: (2)
Event ID: 17055
Date: 7/3/2006
Time: 8:54:12 AM
User: N/A
Computer: SRVCA2
Description:
17052 :
This SQL Server has been optimized for 8 concurrent queries. This limit
has been exceeded by 19 queries and performance may be adversely
affected.
SQL Server worked fine before this. I replaced hard disk and rebuild of
configuration was sucesfull. In SQL events i saw that SQL Server has
performed recovery of databases.
I have SQL Server Personal edition installed.
Can someone help me with this one please.The verion of the db engine shipped with the Personal Edition has an inbuilt
restriction , that once more than a certain number of activities pass the
restriction.
There are a number of different activities which contribute to the count.
Check DBCC CONCURRENCYVIOLATION to gauge how often the service goes over
the limit. Maybe you could upgrade

Most likely the slower diskI/O during the failure was the cause here.
You may want to upgrade to something like SQL 2005 Express which removes
this particular restriction. (but has others).
