Subject kafkaspout is very slow
Date Tue, 03 Feb 2015 12:03:07 GMT
Hi all,

In my topology,  kafka spout is responsible for over 85% of the latency. I
have tried different spout max pending and played with the buffer size and
fetch size, still no luck. Any hint on how to optimize the spout? The issue
doesn't seem to be with the kafka side, as I see high throughput with the
simple kafka consumer.

thank you for your feedback
