Re: Is cygwin much slower on Core 2 Duo
Hmm... I don't quite know what to say. Some people are just inherently abusive.

I have read the archives.

No, the Dotham series is not dual core.

I have tried to find information about this problem but have ended up short. I
have seen a lot of complaints lately on the mailing list about cygwin being
slow, more than I can remember ever before. Maybe this is all related.
I have used cygwin pretty much daily since its earliest days in the mid nineties
but never seen it behave like this before. The reason I'm suspecting the dual
core architecture is because that is the main difference between these two
machines. The rest of the programs I have pretty much just transferred from the
old laptop to the new one.
Any help would be appreciated. If other people on the list are able to run Core
2 Duo systems without any problems at least I would know that it has nothing to
do with dual core hyper-threading issues. But I still need to find out why
suddenly cygwin is so much slower and actually crashes my computer several times
