ACE slowness issue when one server goes down

Unanswered Question
Nov 17th, 2008

Hi,

We are having two application servers.Both are load balanced using ACE.

When we bring down one server, we find that when we upload some files into the second application server, its too slow.

But when primary server comes up again the performance increases.This issue happens only when we bring the primary server down.

We are using cookie based stickiness.Any ideas where we can look into.

Rgds.,

Sachin

Depending on the load-balancing algorithm or predictor that you configure, the ACE performs a series of checks and calculations to determine which server can best service each client request. The ACE bases server selection on several factors including the source or destination address, cookies, URLs, HTTP headers, or the server with the fewest connections with respect to load.
