Hi Stan,

Thanks for posting in community. Based on my understanding, your serviced
component(COM+ , written in c++? or ..) used to be deployed as server
application and because of the speed considerance, you changed it to
library-activated. However, you found this turn the database service into
blocking , yes?

Have you tried providing a certain test application to test the
ServicedComponent both under Server-activated and Library-activated mode?
I'm not sure whether you've ever read the following tech article, it has
discussed on the performance comparsion on COM+ data access components:

#Performance Comparison: Transaction Control

=true

Also, I here are some other ones instruct us on creating own Performance
Monitor coutners for COM+ apps and debuging COM+ apps:
#Creating COM+ PerfMon Counters to Monitor COM+ Data

Maybe you may have a monitor focus on the components (out of the ASP.NET
app) to see whether we can find the root cause. Please have a check on the
above items. If you have any findings or further questions, please feel
free to post here.
