Still getting huge Einstein files!

(moderation:
OK -- Now my downloads are over 300 hours long! I thought that new versions of BOINC/Einstein would take care of this problem. I just downloaded the newest version, 5.10.13, and my latest Einstein is 312 hours! By the way, after reading an earlier response to this problem, I've set my connect to network for every 0.1 days (not that that helped any!)
I have aborted 3 previous work files because I just couldn't finish them, even running 24/7! Why do I keep getting these huge files??? I like the project, and UWM is my Alma Mater, but if there's no way to get reasonable (like 100 hours) data files, I'm going to have to give up on Einstein!
By the way, yes, the completion time appears to be accurate, as my computer's been crunching the data for 4 hours, and I'm just 1% done!!! No way I can finish in the two week timeframe. GET REAL GUYS!!!

Hi!
Given the performance of your computer, I'd expect a CPU time of 100 h and not much more. 300 or 400 h is far too much.
Is it possible that something else is using CPU time on your system?
Do you have the Einstein@Home screensaver active (or ANY screen-saver that does complex graphics?) ? Well, for older machines, this is not advisable, it's just too CPU hungry. In this case, try to change to a "blank the screen only" screensaver and your expected CPU time will decrease towards a more practial 100 hrs, hopefully.
Please let us know if this helped.

If is just the estimated time to completion, it may not be accurate. A few factors going into determining ETA. One is benchmarks. So make sure yours look reasonable. Another is Durration Correction Factor. This can be found on the host page on the web or in client_state.xml.
When adjusting downward, DCF goes down slowly (I think 10% at a time). When going up, it jumps all at once.
I have no idea what a typical DCF should be for Einstein.

Mine is 0.883284, on a slow CPU.

I don't think this is DCF related, see his original post:
I guess there's something else active on his system, like a CPU intensive screen-saver etc.

I think it's because he's running it on an Intel x86 Family 6 Model 8 Stepping 10 800MHz CPU. So that's a Pentium III Coppermine or a Coppermine-128 (Celeron).
Not really something I'd run Windows XP on (in 380MB RAM), or Einstein without significant optimizations to the science application.

The Coppermines are comparatively fast, you should see my ole AMD Athlon 800 under Windows , that's *really* slow and it can still finish even lager WUs in under 100 h :-).

Not if it is a Celeron... I had problems with my 2.3GHz Celeron back in the day. It just lacked the cache to crunch Einstein. And that was the S4 run. I shudder to think about an S5R2 run on it.
Hmmm, are you running Beer@Home? ;-)

Now that you mention it, yes, I'll begin a new WU of B@H right now.

Try Alte Rathaus, Hannover. I tasted it while at CEBIT.

Just checked on this one. At least you have the sense to run Windows Millennium on it, not Windows XP SP2 (even if the OP uses the Home Edition).
And I just noticed your tag. Congrats. When did that happen?
I see JM7 has it as well.
