Hi All, Thanks Tishan for the performance test. The test machines looks having average configuration for the purpose. Hence I think the hardware is realistic.
What we notice here is that 10,000 events per second being the sustainable throughput. Since it seems at this rate CPU is loaded 60%, and plenty of GC happening. Lets assume that on average an API invocation prints four(4) log lines. This means we can sustain only 2500 API invocations on API manager when Log Analyzer is turned on. This looks pretty low and not acceptable figure IMO. We have to investigate where the bottlenecks are, and optimize them so that the log publisher performance closely matches that of APIM/ESB advertised throughput.
