Subject Re: performance Replicated LevelDB vs. SAN
Date Fri, 14 Feb 2014 20:26:41 GMT
I'm testing with ActiveMQ Replicated too (latest SNAPSHOT build) and seeing
similar problems with stability and reliability.  Performance-wise, it
depends on the messaging pattern, number of pubs / subs, message size, and
transaction size.  Also, very dependent on network speed and local disk
speed.

Can you describe your testing env?  Size of messages?  # of clients pub and
sub?  Network speed?

I'm running a 3 node ActiveMQ quorum_mem and 3 node Zookeeper.  

Example test, 1 pub and 1 sub client running on different hardware, 4k
message size, persisted messages, not using transactions, 10G network,
virtual hardware box of 2 CPUs and 8 GIGs memory.

~900 msgs/per sec steady state (pub / sub running normally, keeping up with
each other)
