But anyhow, this is not a negligible difference, and for real large indexes, and busy systems, when the just written non-compound segment is not in the system caches, it might have more effect. Possibly, search performance during indexing would be improved by less indexing IO. Also, delay for addDocument call that triggers a merge should become smaller. Thanks for your comments, also (but not only) on (1) an (3) above.
My main comment is that the benefits of this change can be achieved by using the non-compound index format. For people that care about the difference in performance, it isn't difficult to configure your system to mitigate the problems of the non-compound format, and they probably have already done so. It would help the people who are file-descriptor conscious, but it also increases lucene's fd footprint by a factor of four. -Mike --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
