[jira] [Updated] (LUCENE-2978) Upgrade benchmark from
commons-compress-1.0 to commons-compress-1.1 for 15 times faster gzip
decompression
[ https://issues.apache.org/jira/browse/LUCENE-2978?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Doron Cohen updated LUCENE-2978:
--------------------------------
Description:
In LUCENE-1540 TrecContentSource moved from Java's GZipInputStream to common-compress 1.0.
This slowed down gzip decompression by a factor of 15.
Upgrading to 1.1 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.
