["Robert Muir (Updated) (JIRA)" <ji...@apache.org>]

Robert Muir updated LUCENE-3994:
--------------------------------

    Attachment: LUCENE-3994.patch

Patch, removing n^2 growth in these tests, and some other tuning of atLeast.

In general, when tests like this hog the cpu for so long, we lose coverage overall.

I'll keep an eye on the nightlies for other cpu-hogs.

Here are the new timings for analyzers/ tests after the patch.

'ant test' with no multiplier:
{noformat}
BUILD SUCCESSFUL
Total time: 1 minute 28 seconds
{noformat}

'ant test -Dtests.multiplier=3 -Dtests.nightly=true'
{noformat}
BUILD SUCCESSFUL
Total time: 3 minutes 15 seconds
{noformat}

> The nightly builds are taking 4-7 hours.
> This is caused by a few bad apples (can be seen https://builds.apache.org/job/Lucene-trunk/1896/testReport/).
> The top 5 are (all in analysis):
> * TestSynonymMapFilter: 1 hr 54 min
> * TestRandomChains: 1 hr 22 min
> * TestRemoveDuplicatesTokenFilter: 32 min
> * TestMappingCharFilter: 28 min
> * TestWordDelimiterFilter: 22 min
> so thats 4.5 hours right there for that run....
