Significant speed increase after upgrades

Last night I upgraded all important software on the server of one of our bigger customers. We write all their applications with RIFE and the following sites run on that one machine (all with dedicated admin sections and all public pages being fully dynamic): Netwerk, Dag Allemaal, Genieten, Goed Gevoel, Magnet Magazines, Netcetera, TV-2Weken, TV Familie and Uw Vermogen.

The new software and versions are:

The performance is now really outstanding. Connections are responding instantly, even when a lot of images need to be loaded at once (for instance on the netwerk.be homepage). Note that all dynamic images (magazine covers, avatars, news posts, ...) are served straight out of the Postgres database as a stream. We don't write any lose files to disc from the content management interface.

I'm really happy about this software combination and will start looking into the JRockit management console in a little while. Maybe it can provide some interesting information.

Re: Significant speed increase after upgrades
And before the upgrade you were using ?
Re: Significant speed increase after upgrades
hi there,

it would be nice to know what versions of software you were using earlier. Did you change any configuration for the software ? did you change hardware ? are you using apache/squid now ?

thank you,

BR, ~A

Re: Significant speed increase after upgrades
Sorry, forget to mention that indeed.

RIFE 0.8.2
PostgreSQL 7.4.6
Sun Java 1.4.2_07
Tomcat 5.0.28

Re: Significant speed increase after upgrades
The hardware remained the same, configurations too (just had to make minor changes since the postgres and tomcat configuration files changed a bit). We're serving straight from Tomcat without Apache or Squid front-end by using Linux iptables : http://rifers.org/wiki/display/RIFE/Installing+Tomcat+on+port+80+with+iptables
Re: Significant speed increase after upgrades
Geert, I'm considering to give JRockit a try as well, but am wondering about JAI support (which we need for image support in FOP/Batik). Any clue?
Re: Significant speed increase after upgrades
Hi Steven, works like a charm, all covers here are rotated with afterwards a drop shadow added. This is done with JAI. I uploaded a couple of covers again after the JRockit installation and things just work as before. The installation of JAI is exactly the same as on Sun's JDK.
Re: Significant speed increase after upgrades
So I just take the vanilla install of SUn's JAI and drop it into JRockit, then? Hm - I love it when things are that easy.
Re: Significant speed increase after upgrades
Exactly.
