#TOO MANY INDICES FOR INDEX BUFFER HOW TO#

Be sure you don't also have any leftover calls to setMaxBufferedDocs since the writer will flush 'either or' (whichever comes first). Call tRAMBufferSizeMB() to set the buffer size. Flush by RAM usage instead of document count.ДЇor Lucene = 2.3: IndexWriter can flush according to RAM usage itself.Open a single writer and re-use it for the duration of your indexing session.These devices have come down substantially in price recently, and much lower cost of seeking can be a very sizable speedup in cases where the index cannot fit entirely in the OS's IO cache. If possible, use a solid-state disk (SSD). Get faster hardware, especially a faster IO system.If your index needs to be on the remote fileysystem, consider building it first on the local filesystem and then copying it up to the remote filesystem. Remote filesystems are typically quite a bit slower for indexing. Make sure you are using the latest version of Lucene.So be sure your indexing speed is indeed too slow and the slowness is indeed within Lucene. Many of the ideas here are simple to try, but others will necessarily add some complexity to your application. Be sure you really need to speed things up.
