TrueClient vs. Web HTTP protocol

Hello there,

I have been using LR Web HTTP protocol for years for our application.  I wanted to start using TrueClient because of it's scripting simplicity.  But the response time I am getting with TrueClient is much higher than HTTP protocol.   For example, average sigin-lin response time in HTTP is 2 sec where TrueClient would be 10 sec - keeping the same environment and conditions.  Why it's different in TrueClient?  Is it my configuration or that's the way TrueClient works?  

I would appreciate your experienced opinion with explanation.

Thanks ina dvance,
Akim
