Johan Stuyts commented on LUCENE-639:
-------------------------------------
Yonik, please let me know where you think the test that I provided is flawed. Comparing the
results from your test to the results from my test is like comparing apples to oranges. So
you have to either:
* provide arguments why my test is flawed and provide a better test, or
* run my tests on your machine(s) and publish those results.
> [PATCH] Slight performance improvement for readVInt() of IndexInput
> -------------------------------------------------------------------
>
> Key: LUCENE-639
> URL: http://issues.apache.org/jira/browse/LUCENE-639
> Project: Lucene - Java
> Issue Type: Improvement
> Components: Index
> Affects Versions: 2.0.0
> Reporter: Johan Stuyts
> Priority: Minor
> Attachments: Lucene2ReadVIntPerformance.patch, readVInt performance results.pdf,
ReadVIntPerformanceMain.java
>
>
> By unrolling the loop in readVInt() I was able to get a slight, about 1.8 %, performance
improvement for this method. The test program invoked the method over 17 million times on
each run.
> I ran the performance tests on:
> - Windows XP Pro SP2
> - Sun JDK 1.5.0_07
> - YourKit 5.5.4
> - Lucene trunk
