How can I tune Solaris to run well over a high-latency link?
Solaris seems to default to very conservative tcp stack configuration with regard to running at decent speeds over a high-latency link. Here is some general information on the theory, and some specific resources for tuning Solaris to run faster over such links. Here is a good link showing how latency affects bandwidth, and how to tune Solaris to make it run better on high-latency links. http://www-unix.gridforum.org/mail_archive/data-wg/pdf00000.pdf Here is another page on tuning/diagnosing the Solaris tcp stack. http://www.jimparker.co.uk/technotes/tcp-tuning-solaris.html Candela Technologies, Suite A, 2026 Main Street, Ferndale, WA 98248, USA | www.candelatech.com | sales@candelatech.
