Java seems a bit slow on my 2009.6 system. It takes 5 min to build Sakai, our course management system. Under Linux on the same machine it takes 4 min.
The machine is a Dell Optiplex 960 with a quad-core Intel Q9550 (2.83 GHz) and 8 GB of memory, running 2009.6 as a Xen dom0. (No domU is running during the tests.) I've tried every Java tuning option I can think of. I put the whole build tree on a ram disk to eliminate I/O performance. (That had almost no impact, which is a tribute to ZFS performance.) I've tried the Java that comes with 2009.6, and the latest image from java.sun.com, in both 32 and 64 bit mode. Even more embarrassing, my Mac Pro can do the same build in 3 min. But it's a 2.93 GHz Xeon 5500 quad core, so I think the chip is just faster. Is it expected that Java would be significantly slower on Solaris than Linux? -- This message posted from opensolaris.org _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
