Focus on performance
April 26th, 2009
This weekend brings another snapshot build. I’ve been working mainly on refactoring (exceptions hierarchy) and optimization of critical components like network connectivity, indexing and routing. After a few fixes performance has decreased to something like 80 TPS on one node. I was doing my best to work that out. Thankfully it’s been improved. Tests now run smoothly, all is lighter and more robust.
I have performed a benchmark with JMeter and results finally look promising. On a single node throughput was 659.2 TPS for put w/ Lucene indexing. 999 concurrent threads were storing 20 records. One thing is stability under such load that proves it must be sort of decent and another of course the result itself.
