[Clfswm-devel] Pain caused by daily use.

[Thijs Oppermann]

I too do not have such problems with clfswm, although I use a bit more
powerful hardware it seems. But I use it regularly on three machines, and
they all work fine.

My main home machine is an Intel Core i7 @ 2.67GHz from quite a few years
ago, at work I use an i7 machine a little more recent, and also a very
recent laptop (also a i7, not sure about the speed). The thing is, though,
in all machines I have quite a bit of ram, both work machines are at 8GB,
my home machine 12GB.

Oh, and just remember, I also sometimes use it on my own older laptop core
2 duo with a lot less ram (1 gb? 2 maybe?), and that one works fast too
with clfswm.

Regards,
Thijs
