Further improvements to contrib/benchmark for testing NRT
---------------------------------------------------------
Key: LUCENE-2079
URL: https://issues.apache.org/jira/browse/LUCENE-2079
Project: Lucene - Java
Issue Type: Improvement
Components: contrib/benchmark
Reporter: Michael McCandless
Assignee: Michael McCandless
Priority: Minor
Fix For: 3.1
Some small changes:
* Allow specifying a priority for BG threads, after the "&"
character; priority increment is + or - int that's added to main
thread's priority to set child thread's. For my NRT tests I make
the reopen thread +2, the indexing threads +1, and leave searching
threads at their default.
* Added test case
* NearRealTimeReopenTask now reports @ the end the full array of
msec of each reopen latency
* Added optional breakout of counts by time steps. If you set
log.time.step.msec to eg 1000 then reported counts for serial task
sequence is broken out by 1 second windows. EG you can use this
to measure slowdown over time.
