Tuning Solaris for Performance Benchmarking
The following table shows the operating system tuning for Solaris used when benchmarking for
performance and scalability. These values are an example of how you might tune your system to
achieve the desired result.
TABLE 4–1 Tuning Solaris for Performance Benchmarking
Parameter Scope Default Value TunedValue Comments
rlim_fd_max /etc/system 65536 65536 Process open le descriptors limit;
should account for the expected load
(for the associated sockets, les, and
pipes if any).
sq_max_size /etc/system 2 0 Controls streams driver queue size;
setting to 0 makes it innite so the
performance runs won’t be hit by lack
of buer space. Set on clients too.
Note that setting sq_max_size to 0
might not be optimal for production
systems with high network trac.
tcp_time_wait_interval ndd /dev/tcp 240000 60000 Set on clients too.
tcp_conn_req_max_q ndd /dev/tcp 128 1024
tcp_conn_req_max_q0 ndd /dev/tcp 1024 4096
tcp_ip_abort_interval ndd /dev/tcp 480000 60000
tcp_keepalive_interval ndd /dev/tcp 7200000 900000 For high trac web sites, lower this
value.
tcp_rexmit_interval_initial ndd /dev/tcp 3000 3000 If retransmission is greater than
30-40%, you should increase this
value.
tcp_rexmit_interval_max ndd /dev/tcp 240000 10000
tcp_rexmit_interval_min ndd /dev/tcp 200 3000
tcp_smallest_anon_port ndd /dev/tcp 32768 1024 Set on clients too.
tcp_slow_start_initial ndd /dev/tcp 1 2 Slightly faster transmission of small
amounts of data.
tcp_xmit_hiwat ndd /dev/tcp 8129 32768 To increase the transmit buer.
tcp_recv_hiwat ndd /dev/tcp 8129 32768 To increase the receive buer.
