Solaris 10 Platform-Specific Tuning Information

Solaris
Solaris Operating System (OS). You can use the DTrace Toolkit to monitor the system. The
DTrace Toolkit is available through the OpenSolaris
(http://www.opensolaris.org/os/community/dtrace/dtracetoolkit/).

Tuning Parameters

Tuning Solaris TCP/IP settings benefits programs that open and close many sockets. Since the
Enterprise Server operates with a small fixed set of connections, the performance gain might
not be significant.
The following table shows Solaris tuning parameters that affect performance and scalability
benchmarking. These values are examples of how to tune your system for best performance.

Comments
Limit of process open file
descriptors. Set to account for
expected load (for associated
sockets, files, and pipes if any).
Controls streams driver queue size;
setting to 0 makes it infinite so the
performance runs won't be hit by
lack of buffer space. Set on clients
too. Note that setting sq_max_size
to 0 might not be optimal for
production systems with high
network traffic.
Set on clients too.
