Hi Frederick,
There is an article about tunning the performance of PostgreSQL on
Solaris at
http://tweakers.net/reviews/649/9
which is not quite exactly of what you wanted but it might help you.
I think that Solaris has disk cache turned off by default which linux
does not have
due to possible data loss in case of a power failure.
Regards,
Julo
