Re: High disk write usage

Thnaks a lot alessandro! Yes, we have very big physical dedicated machines, with a topology of 5 shards and10 replicas each shard. 1. transaction log files are increasing but not with this rate 2. we 've probed with values between 300 and 2000 MB... without any visible results 3. We don't

Point 2 was the ram Buffer size : *ramBufferSizeMB* sets the amount of RAM that may be used by Lucene indexing for buffering added documents and deletions before they are flushed to the Directory. maxBufferedDocs sets a limit on the number of documents buffered

Re: High disk write usage
