Hello Alex, unfortunately I can not help with your problem, just one hint:
> - RecentReadLatencyMicros and RecentWriteLatencyMicros are super high > for StorageProxy, as well as every column family in JMX: up > to 43 s and > 9s (see screenshot). However, in cfstats, they are quite small. Remember that the latency values in JMX are in microseconds, whereas cfstats reports in ms. This was changed between 0.5 and 0.6, IIRC. Greetings, Martin
