<p>How much database performance overhead is involved with using C# and LINQ compared to custom optimized queries loaded with mostly low-level C, both with a SQL Server 2008 backend?</p>

<p>I'm specifically thinking here of a case where you have a fairly data-intensive program and will be doing a data refresh or update at least once per screen and will have 50-100 simultaneous users.</p>

Have you tried removing the SSP using the command line? I found this worked once when we had a broken an SSP and just wanted to get rid of it.
The command is:
```
```
stsadm.exe -o deletessp -title <sspname> [-deletedatabases]
```
```
The
```
deletedatbases
```
switch is optional.
Also, check in Central Administration under Job Definitions and Job Schedules to ensure no SSP related jobs are still running
