Hi, I am trying some tests to confirm if single Solr instance can perform over 1000 queries per second(!).
But now, although CPU usage is 40% or so and iowait is almost 0%, throughput does not increase over 60 queries per second. I think there are some bottlenecks around Kernel, JVM, or Solr settings. The values we already checked and configured are followings. * Kernel: file descriptor net.ipv4.tcp_max_syn_backlog net.ipv4.tcp_syncookies net.core.somaxconn net.core.rmem_max net.core.wmem_max net.ipv4.tcp_rmem net.ipv4.tcp_wmem * JVM: Heap [ -> 32GB] G1GC settings * Solr: (Jetty) MaxThreads [ -> 20000] And the other info is as follows. CPU : 16 cores RAM : 128 GB Disk : SSD 500GB NIC : 10Gbps(maybe) OS : Ubuntu 14.04 JVM : OpenJDK 1.8.0u191 Solr : 6.2.1 Index size : about 60GB Any insights will be appreciated. Thanks and regards, Yasufumi.
