Can anyone remember specific information?
The only detail I remember about performance under Solaris is a discussion
about slow qsort:
http://archives.postgresql.org/pgsql-hackers/2002-04/msg00103.php
A quick search didn't turn up information about whether the build
process now replaces Sun's qsort, or whether Sun has improved qsort
since the problem was noticed by postgres users in 2002.
It'd be interesting to invest some time studying the sources at
opensolaris.org.
