------------------------------------------
Hi Guillaume,
yes I've deployed a fresh 4.1.0-SNAPSHOT to the Maven repository (after Hardy merged
this in master)
The numbers above refer to an ext4 partition using default settings - but if you want to
try to experiment with the write barriers, these are the "tuned" settings I
usually use on the SSD drive on the laptop:
rw,noatime,commit=60,max_batch_time=0,barrier=0,data=writeback
These should provide better performance (that's why I use them for coding), but I
don't suggest using them in a production system: I'm not a filesystems expert,
have just been playing with them especially because of the write barriers you mention.
Profile mass indexer to reduce number of index commits
------------------------------------------------------
Key: HSEARCH-1019
URL:
http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-1019
Project: Hibernate Search
Issue Type: Improvement
Components: massindexer
Affects Versions: 4.0.0.Final
Reporter: Hardy Ferentschik
Assignee: Sanne Grinovero
Priority: Blocker
Fix For: 4.1.0.Alpha1
We need to profile the new mass indexer design and try to reduce the number of index
commits. Performance of the filesystem based directory declined to a bug fix in Lucene
(
https://issues.apache.org/jira/browse/LUCENE-3418). Trying to reduce the amount of index
commits (and hence fsync calls) might alleviate the performance loss.
