Maybe uplinger wishes to update the sticky post at top of this forum that answer part of your question. Update, because the A-Type will run 1/5th of the time than before with only 10 of 50 loops. The C type I think will then take over a part of that i.e. will run longer than originally set out on project launch.

As for the resources, refer to the System Requirements help page and the Matrix FAQ for actual observed resources. It's needs also updating due to new sizing.

Right, but in my case I was comparing Ubuntu 64-bit vs XP 32-bit, so it was just confirming that 64-bit is faster than 32-bit (which was not accepted by everybody at this time).
For comparisons between Linux 64 and Windows 64 you should be more able than me to give at least your feeling since you have a Win 64 device now.

i did not get any ddt2 wu since a month or more.
I tried to unsubscribe all projects except ddt2 and rise the cache to 10 days... no wus downloaded...

This tactic worked for me. You still need to 'babysit' though, and refresh often, like every 30 seconds.

herna, right from the word 'go', the WCG techs said that there would be dry spells in this particular project - and I haven't heard anything to the contrary...

Basically, there's a manual step involved between each phase, and thus, as the scientists (like the rest of us) are only human, they need time to sleep, eat, take holiday's and actually evaluate the last results/prepare the next stage WU's etc. Thus, the dry spells...

Obviously, the techs themselves will be able to give a better assessment as to whether there'll eventually be longer spells of rain or not - or whether this project will run like it currently is doing, right up to it's conclusion.
