Hi everyone!
This week I've been playing with DraftSight both on Linux and on
Windows. DraftSight is a Qt4 CAD drawing program that is very similar
to AutoCad and it is available for free both for Windows and for
Linux.
Like you I use DraftSight on PCLoS.
I used DraftSight for many months on Linux on my Core
2 Duo with 2gb
of RAM computer and it is sluggish. Each time that I select a part of
the drawing to modify an attribute there is a 5-10 second delay
before the program unfreeze.
I find the same problems ! Maybe not quite as severe but certainly the
graphics performance leaves something to be desired. I'm currently
running a dual core 3Gig P4 with 1Gb ram.
On my Windows-only laptop that I use mainly for
running industrial
automation software, I have installed DraftSight this week. This
laptop is an old IBM ThinkPad A31p with a 1.7GHz Pentium 4 cpu and
512mb of RAM. It runs Windows XP. On this laptop, DraftSight runs
perfectly well and there is no delay when I click on a part of a
drawing, even if it is a much slower computer and the general
performance of DraftSight is much better on Windows.
On my laptop, a 1300Mhz 1Gb running Open SuSE 11.1, DraftSight runs a
lot more smoothly without the jerky mouse and refresh delays.
Is there a reason why I see such a big difference
between this Qt4
program on Linux and on Windows? Does the difference is because of
Qt4 or it could be because DraftSight has not been ported as well as
it could be?
?? That could be a question for the DS developers.
Qt3 has a very high performance and on a slow
computer, it is even
faster than GTK2. The UI element are drawn faster than almost every
other GUI toolkits. Why does QT4 still suffer from these performance
issues?
Have an happy spring break!
