COMMENT 'table "terms"' + +To execute offline index construction, execute `DISABLE KEYS`, then `ENABLE KEYS`. + +#### Improved performance on multi-threaded + +This improvement is not Mroonga itself, it's derived from [Groonga 4.1.1](http://groonga.org/en/blog/2015/01/29/release.html), now multi-threaded performance will be improved if Groonga is built with --with-jemalloc configure option. + +This is experimental feature, there is no package for each distributions which enables jemalloc by default. + +Anyway, please give us feedback about this improvements if you can try it. + +### Conclusion + +See [Release 4.10 - 2015-01-29](/docs/news.html#release-4-10) about detailed changes since 4.09. + +Let's search by Mroonga! -------------- next part -------------- HTML����������������������������...Download
