Two months ago, when I last built Code::Blocks with autotools, it was using -O2.

hendrik:
So I'll just check out if building by hand leads to an optimized build or not.

hendrik:
Sorry for double-posting guys, but I just compiled the most recent svn checkout using GCC 4.1 on my Ubuntu 6.10 Box with -O3 and -march=athlon-xp parameters (Standard configuration is -O2), which solved none of my problems. The editor's still lame, using about 50% of the CPU while typing, with all plugins disabled.  :?

Klaas:
I seem to have the exact same problems with codeblocks on ubuntu dapper. When moving the mouse in the code window, the processor load exceeds 50%. Scrolling thru the code also feels sluggish and make the load go up to 100%. Disabling all the plugins didn't solve the problem.

I'm using nvidia drivers, the November 23 build of Codeblocks and wxWidgets 2.6.1 on a AMD 3200 (in 32-bit mode).

Hello.

I have the same problem with my Kubuntu 6.10.
I have read all the posts about linux performance issues and I can't find a pattern.

This problem doesn't seem to be related to (K)Ubuntu in particular, Debian users have the same problem.
I could reproduce the 100% CPU usage issue even using Suse 10.0, which was running from inside QEMU (the 100% CPU usage was INSIDE the emulator, that is, in the emulated OS). I believe this test leaves (k)ubuntu and my particular hardware out of the question.

I want to help to solve this bug, because I find codeblocks very useful.

Profiling tips are welcome, because it would be best to profile (with gprof) as little cpp's as possible, to keep the profiling meaningful.

Another interesting thing to do, is to gather details about the harware and distro of users with (and without) the problem.

We could open a topic and organize all this...
Anybody in?
