Upgrade benchmark from commons-compress-1.0 to commons-compress-1.1 for 15
times faster gzip decompression
----------------------------------------------------------------------------------------------------------
Key: LUCENE-2978
URL: https://issues.apache.org/jira/browse/LUCENE-2978
Project: Lucene - Java
Issue Type: Bug
Components: contrib/benchmark
Reporter: Doron Cohen
Assignee: Doron Cohen
Fix For: 3.2, 4.0
In LUCENE-1540 TrecContentSource moved from Java's GZipInputStream to
common-compress 1.1.
This slowed down gzip decompression by a factor of 15.
Upgrading to 1.0 solves this problem.
I verified that the problem is only in GZIP, not in BZIP.
On the way, as 1.1 introduced constants for the compression methods, the code
can be made a bit nicer.
