Hi,
I'm using IP tunnelling to load balance HTTP requests from the director to 44 real servers. The real servers are all in different subnets of an ISP.
I'm seeing 500-800 ms more latency when accessing the web service via the director than going directly to the real servers. Any ideas on why this would be happening?
The real servers are lightly loaded and I've tried all the different load balancing options (rr, lc etc).
