My 400mhz computer takes about 7 hours to crunch a short WU and only get about 5 - 8 of credit compared to my BEAST 3Ghz which gets 8 - 12 of credit where it only takes a hours to complete. The 400 uses linux while the beast uses winxp pro.

William, look at this url, and look under what it says about Linux.

Scotty, I need more power!!!!

this is one of the great problems of ALL BOINC PROJECTS (seti,predictor,lhc...)
different CPU s and Different OS give differend Resultats at the SAME WU
you can read it at all boards or forums of the Boinc projects

But the processor is of the beast is nearly 8 times as fast...

The linux BOINC client is horribly optimized. This causes the benchmark scores to come out very low and because of that, the claimed credit is very low. The answer is to recompile the BOINC core client yourself with better optimizations. See here for step by step instructions on how to do this. It only takes a few minutes (assuming you have the correct libraries installed :) This should nearly double your benchmarks scores and bring the claimed credit at least somewhat close to that of windows boxes.

Thank you for your sugestion i will try it out.

I have compiled boinc my slef but now i get "Message from server: platform 'i586-pc-linux-gnu'" is there a way of changing it or too fool the server.

Not sure (since I never compiled BOINC myself), but you need to follow a strict procedure (Anonymous Platform) to implement self-compiled Platforms, as laid out on the BOINC Page :
http://boinc.berkeley.edu/anonymous_platform.php

Some of it talks about manually creating/editing the app_info.xml File for the Server to recognize and accept your compiled Platform it seems.

If you did all that already, I'm not sure where an error might have occured (?)
I know the Procedure is reportedly working just fine for SETI, but other Projects (e.g. LHC) might be self-limiting communications/distribution of work to officially relased BOINC Versions (unsure)

Right now, LHC would probably be a bad Project to test it, since they're out of work. Your platform compilation definitely sounds 'okay' to me in any case.
