Re: [infinispan-dev] poll on self-tuning ISPN / JGROUPS paramters

Rehashing timeouts! (rehashRpcTimeout) Erik -----Original Message----- From: infinispan-dev-bounces(a)lists.jboss.org [mailto:infinispan-dev-bounces@lists.jboss.org] On Behalf Of Paolo Romano Sent: Thursday, July 21, 2011 3:21 PM To: infinispan-dev(a)lists.jboss.org Subject: [infinispan-dev] poll on self-tuning ISPN / JGROUPS paramters Hi, in the last Cloud-TM's meeting in Rome we have discussed the idea of posting a poll asking to ISPN's users which parameters they consider more complex to tune, or which parameters they consider as more important to be self-tuned. Before we post the poll, however, we thought to first ask you if you think that we could suggest also different parameters. The current list of parameters includes: - size of the marshalling buffer - frequency with which replicationQueue (for asynchronous acks) is processed: - clustering->async-> replQueueMaxElements - clustering->async-> replQueueInterval -number of max concurrent transactions (currently this is unbounded, but we could self-tune the multi-programming level to maximize performance depending on the number of available cores, the actual conflict rate among transactions etc.) -lock striping, also adapting size of lock pool (striping can lead to false sharing, but reduce the memory footprint and the size of the exchanged messages) -adaptive timeout for deadlock detection, based on the avg duration of a transaction/conflict rate etc Any suggestions?
