I ran some tests on my dual-Xeon machine to see what speedup using parallel gmake. After two builds to warm up the cache, I saw when alternating gmake and gmake -j2:
gmake 0m57.207s gmake -j2 0m44.305s gmake 0m58.691s gmake -j2 0m33.979s As you can see, gmake -j2 is ~35% faster than gmake without -j. I will be using -j from now on. -j3 shaves another second off. FYI, I also use ccache for compiles. -- Bruce Momjian <[email protected]> http://momjian.us EnterpriseDB http://enterprisedb.com + It's impossible for everything to be true. + -- Sent via pgsql-hackers mailing list ([email protected]) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
