Lubuntu not getting the same BOINC points as on XP

[Rouxenator]

I played around with Ubuntu on a old 2Ghz P4 that I had laying around and after two days of sluggish Ubuntu performance I switched to Lubuntu and then left the PC running BOINC for a while.

Look at the Best five days scores it seems that the computer is less productive running Linux than it was on XP SP3.

The machine is the exact same, the only difference is that I loaded Ubuntu on it after having XP on it for a long time.

Stats running XP SP3 :

Stats running Lubuntu 10.04 :

Any ideas why this is the case ?

Might be the client that is less optimized for the Linux kernel? Maybe try one of the clients in the last link below, and check again?

Found some info on "optimized" clients:

Thanks, so I can just download them and double click to install ?

Maybe due to not running as long?

Could be, but the average points is a lot lower than on XP if you look at the graphs... Maybe its a RAM issue - XP is fine with 256MB or more but for all the nice new stuff in Ubuntu I think 1GB is probably a better bet.

Thing is, if you look at the best five days, the results are quite scattered. These aren't really statistically significant, because it simply takes a single fantastic day, and it could sway the results.

If you look at the average credit per CPU second, a different story is told. While the Lubuntu gives a lower amount, the difference is only around 2%.

Ultimately the only way to tell is to run them for equal amounts of time to see what the results are.

Well its the same box and it no longer has XP on. Therefor the average (calculated over the last 30 days) will drop to 0 soon. the Top days is therefor the only historic measure of strength. I will see if I run the Lubuntu for longer if it gets any better.
