Hello, Erik. Thank you for answering. The performance decreases during indexing: while replication is in process the batch machine could not recieve and process quickly the indexing petitions and some "read timed out" exceptions appear. Luckily I just load some hundreds of documents every day because it isn't a batch operation itself (I just index daily the new documents recieved), but in those minutes the batch machine seems unable to operate correctly. The machines are in the same LAN, so I think that it's not a connection performance problem. Is it posible that the batch machine has I/O HDD problems while reading and writing into disk at the same time?
Thank you very much.
