Hi Shawn, thank you for your reply.
I'll check if network card drivers are ok. About the RAM, the JVM max heap size is currently 6GB, but it never reaches the maximum, tipically the used RAM is not more than 5GB. should I assign more RAM? I've read that excess of RAM assigned could have also a bad effect on the performance. Apart of the RAM used by JVM, the server has more than 10GB of unused RAM, which should be enough to cache the index. About SolrCloud, I know it doesn't use master-slave replication, but incremental updates, item by item. That's why I thought it could work for us, since our bottleneck appear to be the replication cycles. But another point is, if the indexing occurs in all servers, 1200 updates/min could also overload the servers? and therefore have a worst performance than with master-slave replication?
