Making RTC run more efficiently


Andy Armstrong (1126) | asked Apr 20 '12, 11:49 a.m.
Hi folks!

I am running RTC with RTS on Ubuntu 10.04 LTS *I know this isnt supported* - I have used a fix from a bug about too many open files to get this far.

The computer I am using is not massively powerful:

1.8ghz celeron with 768MB ram.

I am finding response times nearly unbearable when using the web pages or eclipse ide. When I look at htop on the ubuntu servers its stating the CPU is barely used - but memory is almost empty with 707/717 MB constantly used - 90% of that is the java process running RTC server. I feel this is the reason that the service appears very slow - as the CPU isnt being utilised and it is not the network.

I dont know what I installed, and I may have other things i dont want or use running as well - for instance QM etc - **cannot remeber the names**

Can anybody tell me how I can turn off everything I dont need - all I want is CCM.

Cheers,

Andy

I personally wouldn't try running a server with less than 2 gigabytes of ram available for use by the server.

In your case, you have to either have more phsical memeory or enlarge your swap and configure your RTC server to have a large heap. 768 is too small, I'm not sure whether any one had run with that.
