I talked to the lead developer for JRockit months ago and he told me they take the code from Sun releases and add it to all the releases. What that means is thier 1.4.x is as fast as the 1.5.x but the difference is functionality they do not port 1.5 functionality to 1.4.x.
This is important to me because you may be able to do an upgrade for 1.4.x of Jrockit in production for say BEA and get the performance of 1.5.x. I do not believe Sun does that. Especially since I was interested in performance inprovements of 1.6.0_02 at the time and was wondering what release BEA was going to put that into. Sun has a performance paper about the improvements of 1.6.0_02 over earlier releases and I saw that exibited on a system I engineered so I knew it to be true and was wondering when BEA was going to incorporate the 1.6.0_02 code from Sun. -Tony --- Leon Rosenberg <[EMAIL PROTECTED]> wrote: > Hello, > > i have tested synchronized vs. atomic performance > two years ago with > both jrockit and sun 1.5, both 32 bit, and > jrockit was clearly faster in synchronization and > slower in atomics. > But its of cause its far outdated. > > http://moskito.anotheria.net/AtomicVsSynchronized.html > > regards > Leon > > > > On Tue, Jun 17, 2008 at 8:02 PM, Peter Lin > <[EMAIL PROTECTED]> wrote: > > I've compared JRockit 1.4 and 1.5 in the past > against SUN and it was > > faster for synthetic benchmarks. > > > > I don't work for BEA, but I do like JRockit.
