RecentReadLatencyHistogramMicros vs. latencies in client

2012-01-17 Thread Marcel Steinbach
Hi, we're running a 8 node cassandra-0.7.6 cluster, with avg. throughput of 5k reads/s and almost as much writes/s. The client API is pelops 1.1-0.7.x. Latencies in the CFs (RecentReadLatencyHistogramMicros) look fine with 99th percentile at 61ms. However, on the client side, p99 latency is at
