I have this pc with kubuntu and it gets really slow when I run programs like eclipse or talend. I know those two are memory hogs but I have 6gb ddr3 (it does not say in the list but it's ddr3) and sometimes it's not all occupied and I the computer really slows down.
Also I think there is a problem with apache solr and kubuntu. When I run apache solr, apache uses 5gb of ram. In ubuntu server (with less memory and less cpu power) the same solr queries only make apache take up a few hundred mbs.
Here is the hardware list given by lshw, please tell me if any component is incompatibel with ubuntu: http://pastebin.ca/1995800 (couldn't post it here because it was huge)
java version "1.6.0_20" OpenJDK Runtime Environment (IcedTea6 1.9.1) (6b20-1.9.1-1ubuntu3) OpenJDK 64-Bit Server VM (build 17.0-b16, mixed mode)
I am using this java version and it's the same as in my ubuntu server machine which runs apache and solr without a problem.
