Webdispatcher Tuning - Connection times

Hello All,

We have configuration where ECC system connects to ADS System via Webdispatcher. (ECC and ADS both are 2 node cluster)

I have observed that connection time from ECC to ADS via Webdisp is much higher than without use of webdispatcher.

Landscape Info: SAP Webdispatcher 7.20 on Windows 2003

E.G

======================================

Case 1: ECC --> ADS

SM59 connection test time: 24 ms

======================================

Case 2: ECC --> WEBDISP--> ADS

SM59 connection test time: 2100 ms

======================================

As can been seen, when I use Webdispatcher connection time almost 90-100 times higher. This leads to performance degradation.

I want to use Webdispacher to balance load among 2 ADS cluster nodes.

Can you please suggest suggestions here so that connection times can be tuned?

Thanks.
