Write throughput is low !!

Hi All,

We, at our company, have a modest Zookeeper lab setup with 5 servers.

During our lab tests, we found that somehow we can not go beyond 5K Writes/Sec in total with roughly 100 clients (all the clients issues writes to different znodes in a tight loop). Can someone point me to the official numbers? Is this a good number for Zookeeper or it can scale much beyond?

I understand that, parallelization by writing to different znodes will not increase the throughput as there is only one log underneath.

PS: Lab is hosted on a high speed network (1gigbit/sec) and network latencies are far lower in contract to the the numbers we have.

Thanks
