I've never had to deal with GC tuning since our cluster has relatively few
(but large) columns. So I'll leave further comment to others, but it sounds
like you're on the right track.

First to be clear, I'm not an expert but I suggested "cfstats" because it
can show unhealthy signs. That said, yours looks okay to me: few live
SSTables per column family, reasonable quantity of data... The next things
I'd verify are that (1) the JVM isn't swapping out during these periods of

Hi Dan,
Thanks for answering.
I included the output of cfstats below.
I hope you can say something about our problems with it.
cheers,

We are in the process of upgrading to 1.x, but can't do so for a while

some performance issues.
We are getting timeouts
