Hi,

Now that I've got all the Linux proponents all worked up, here's my story:

During the past week, I upgraded my main PC on which I run Win2K. According to BoincView I got about 11.2 credits/hr running W2K on the pre-upgrade machine (AMD64 3000+).

After the upgrade I used the AMD64 3000+ mobo and chip to build a machine on which I installed Fedora Core 4.

Now BoincView shows that the credits/hr dropped to about 6.7.

Why this dramatic drop? The only differences are going from a 160GB to 40GB HDD and from 1.5GB RAM to 256MB. Surely that can't be the cause of such a dramatic drop in performance? It's more depended on the CPU than anything else if my logic isn't flawed?

I've seen this drop in actual credits/hr processed as well.

Any suggestions for a Linux novice?

Thanks!

Linux slower than Windows

Linux client is a little slower than windows. But there
was a great improvement with the latest app.

How does the run time/workunit under Linux compare with the run time/workunit under Windows?

V7, The biggest reason for

V7,

The biggest reason for your drop in average credit is the delta in BOINC benchmarks between windows and linux. BOINC benchmarks under windows are much higher than linux (same hardware). Claimed credit is a result of your benchmarks, so a linux machine will claim less credit then a windows one (same hardware). A sad fact, but one we've had to live with.
