Sun Java System Web Server 7.0 Update 3 Performance Tuning, Sizing, and Scaling Guide

Web Server Start Options

In some cases, performance can be improved by using large page sizes. To start the 32–bit Web Server with 4 MB pages:

LD_PRELOAD_32=/usr/lib/ ; export LD_PRELOAD_32; export MPSSHEAP=4M; ./bin/startserv; unset LD_PRELOAD_32; unset MPSSHEAP

For 64–bit servers:

LD_PRELOAD_64=/usr/lib/64/; export LD_PRELOAD_64; export MPSSHEAP=4M; ./bin/startserv; unset LD_PRELOAD_64; unset MPSSHEAP
