Sick of all those MSDE questions that are all the same? Ever wanted the definitive answer on just exactly how MSDE limits performance and scalability? Well, youre in luck, as Microsoft has now published a whitepaper describing how the governor in MSDE works.
http://www.microsoft.com/sql/msde/techinfo/workloadgov.asp
In summary the paper describes how the governor stalls connections for a few milliseconds on each logical read or write, once the limit of more than eight concurrent operations has been reached. The connection limit for MSDE is the same as for a standard SQL Server instance (32,767), but obviously the more concurrent connections, the more likely you are to reach the limit of 8 concurrent operations that triggers the workload governor.
