That's surprising, I'd say that in 30 mins of invocations all the critical paths are touched much more many times than 10000. E.g. the number of reads/sec is in thousands (20k on the cluster lab). Might be that this param is ignored or it collides with other -XX ? _______________________________________________ infinispan-dev mailing list infinispan-dev@lists.jboss.org https://lists.jboss.org/mailman/listinfo/infinispan-dev
