I'm wondering if anyone has tested Lucene indexing/search performance with different file system block sizes?I just realized one of the servers where I run a lot of Lucene indexing and searching has an FS with blocks of only 1K in size (typically they are 4k or 8k, I believe), so I started wondering what's better for Lucene - smaller or larger blocks? I have a feeling 1K is too small, although I don't know enough to back up this feeling. :(
If you want to boost performance, changing the readahead size on the device will probably help, if not tuned. Use the 'blockdev' command on linux to tweak this.
