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.

    Hi,

    There is not much that can be tuned w.r.t. to the connection times, and there shouldn't be a need for it. Could this be a network issue? E.g. network between ECC and WEBDISP or between WEBDISP and ADS is slow?

      Hi Billy,

      I have performed tracert from ECC system to both ADS and Web-disp host. Both are having same router hops. Hence, does not seems to be anything wrong at network level.

      Also, both ADS nodes have exact same config for number of Server processes, heap etc.

      Hi Tobias,

      I have checked Response time values in Web admin Interface. There is difference between both the nodes' values. Node 2 (651ms) has slightly higher response time of Node 1(581ms).

      Node 1:

      Response times (us)

      Last 582174 Avg 581446 Min 2967


      Node 2:

      Response times (us)

      Last 648945 Avg 651394 Min

      2452

      However, above response times are not that huge that I get ard 2100 ms response time via Webdispatcher and that also just checking RFC in SM59. (not even loading pdf form).

      Any other area to check for?

      Thanks.
