I did already set that to the number of cores of the machines (24), but

I continue to suggest that you file a JIRA ticket... I feel you have done
sufficient community based due dilligence
for storing data.

Hi,
I am currently performing benchmarks on Cassandra. Independently from each
other I am seeing ~100k writes/sec and ~50k reads/sec. When I read and
write at the same time, writing drops down to ~1000 writes/sec and reading
