The diagnosis in the forum is incorrect and built from bad assumptions

I'd say the diagnosis in this thread is 100% correct... The GUI applications are not working properly... ;)

(But it was nice (no pun intended) of the developer to chime in and provide us with the reason why.)


The problem is not only with the GUI tools. Despite seti are reported by ps to have a 19 (lowest) priority, they are competing with prio 0 tasks. When I run compute bounds tasks (they matlab or idl), they are slower by a factor 4 when seti is running (macpro 4 cores, 4 seti clients). 10.5.2 is still wrong. 10.4.11 is ok: the impact of seti on computations is low, say 10%. There is a problem with 10.5 scheduler.


Has any one reported this to Apple?

On a positive note:

It was 'nice' of Apple to bring back the docks hierarchal menu feature... Now we can get to all our broken apps... ;)
It may not be 1984 but George Orwell sure did see the future . . .
