I tried running my latency tester against trunk, in so doing I noticed that the C/Python (not sure which yet) client performance has seriously degraded since 3.3.3.
The first run (below) is with released 3.3.3 client against a 3 server ensemble running released 3.3.3 server code. The second run is the exact same environment (same ensemble), however using trunk c/zkpython client.
1) in the first run operations are approx 10ms/write, 0.25ms/read - which is pretty much what's expected.
2) however in the second run we are seeing 50ms/operation regardless of read or write.
