Datal,
Please post the performance rating for your machine. You can view both the overall and the component scoring. The overall machine rating is made up of a weighted average.
Processor is the most important. Memory and Network next, and HD Allocation is the least important in ranking.
Looking at your specifications, you probabably have ~50 on CPU, ~150 on Mem, ~200 on Storage and are getting smoked on the dialup. You can't do much more tweak it, other than a faster connection.
The way the points work is: if machine A is twice as fast as machine B, machine A will score twice as many points per cpu time. However it takes half the time to do the job. In numbers, lets say A rates a 30 and B a 15. Both computers work for 10 hours. In that time A has completed 2 tasks (5 hours for each) and B 1. A gets 30 pts x 5 = 150 pts for each task x 2 tasks = 300 points. B gets 15 points x 10 hours = 150 points.
They both earned the same number of points per task, 150 points. But since A did it in half of the time, A did a second task and earned another 150 points.
Comparing the stats of the example, The average number of points per task is the same 150. But the average number of points per cpu hour is 30 vs. 15.
There are some quirks about the scoring system, but that is how it is supposed to work. Different systems should round out to earning about the same per task...such that a slow older machine can still churn away on a work unit, and a new blazing comp can crank them out. The more you get done, the more points you earn.
Improve you score by processing more units (improve performance), or by adding additional machines (I have 2 machines running pretty much continuously).
