Runtime: how about increasing it

[Johnmark]

I'm beginning to think the methodology for max. production numbers being posted is flawed. There is no doubt that running CPU tasks with GPU will slow down production, that is a given and makes sense.

However on the subject of GPU only crunching something isn't adding up!

A while back I was running 16 wu's on 79xx and 8 on 7770's. Someone said that 10 was optimal for 79xx cards so I dropped mine to 10 and added another 7950 and 7770 to the farm. After adding those cards my point production barely went up and stayed around the 530k mark for. So I'm reading this thread a couple of weeks ago and decided to put the 79xx's back to 16 wu's, then 24 were they have been running for just over a week. I've seen my PPD production jump up significantly since then averaging well over 620k ppd, nothing else changed(have a look at the pie chart). I'm not doing any fancy math trying to figure out immediate production or anything, just looking at BOINC stats and free-dc. Also my pending where increasing throughout that last period, I see today that pending's are finally coming down from the 600 page mark.

So what the heck is going on, my PPD is not jiving with what other people are seeing/saying ? Like I've always said I really care less about points other than their indication of work done, but I find this to be odd.

FWIW my current farm consists of 1-7970, 2-7950's and 5 7770's, all running on Quad core's with hyperthreading.
