What I have

I have a cloud service with a Worker Role who uses a TCP/IP endpoint.  This service hosts one of my .dll logic libraries to run code against a Azure SQL database I  have hosted.  Everything is up and running fine.  I manually create my own logs and I have verbose logging turned on as well.

What I do

Recently I tried to do a load test by spawning threads in a for loop.  I used a long running process (5+ seconds) and have a new thread kick off every 50 milliseconds. 

Where I am

I have logs set up in my worker role which record each access.  I record the start and end time of each call.  For whatever reason the first 2 calls seem to be asynchronous, but after that one call doesn't start until the call before it ends, which takes about 5 seconds per call.

Also, when I look at my service dashboard I can only see processing time.  I would like to see the number of connections and other data about the service.  

How to help

Any specific information you can give to guide me would be greatly appreciated as would relevant up to date online resources.  One problem with online information on Azure is that I've found a number of outdated resources or pages that were removed and only link to other pages that were removed.  

My Custom Logs

Logs are ordered by timestamp, and I would expect them to be 50 milliseconds apart, not 5 seconds apart.  Also, at this time I don't know why some calls are made is less time than the code took to run.

Could you please show us some sample code of how you connect to your service. The problem doesn't have to be server side. For instance if you use the same client connection in multiple threads, it will also just use one server connection (and since there is just one connection, processing goes one at a time).

Also, is the problem Azure specific? Can you run your worker locally with multiple threads?
