Hallo, on our team board we discussed about crunching time of Convolution Work Units. We compared two machines and results are interesting.

'bosh - AMD X2 4200 Windows XP
WU-------h--m--s
gs_72... 00:19:39
gs_70... 00:19:41
gs_62... 00:05:26
gs_60... 00:05:25

LiborA - AMD A64 2800+ OpenSuse 10.3 64b
WU--------h--m--s
gs_74 ... 00:13:39
gs_73 ... 00:13:31
gs_72 ... 00:13:43
gs_72 ... 00:13:34
gs_71 ... 00:13:29
gs_62 ... 00:05:26
gs_60 ... 00:05:24

It seems that for non-convolution Work Units the application need a similar time for the WU in the same range. But for Convolution Work Units is linux application a more, more effective.

It looks like the windows application isn't being compiled as well as the linux one. The problem behind this might be that the linux is using a 64 bit binary (where i'm pretty sure the windows does not). We're working on getting a 64-bit windows system to compile on which will hopefully improve the times on windows.

Are you sure? I have downloaded astronomy_1.13_i686-pc-linux-gnu executable, it seems as 32b application? And on download folder isn't x86_64 application available.

Its a very good message for all users of 64b Windows OS :-)
