Hi, for a PerCall WCF service whose throttling has been set to be high (say, 200 max concurrent calls) would WCF bring up a new instance and invoke the request on a threadpool thread?

If it does, then does this have an impact on the total number of concurrent calls allowed?

I ask because I don't seem to ever hit the max number of concurrent calls I've set in the service throttling config but instead a fraction of that number - up to 50 on a 100 MaxConcurrentCalls setting and 160 on a 200 MaxConcurrentCalls setting.

Thanks,
