Good day Gentlemen
While debugging my projects in XCode 3.x I realized my 2Ghz iMac is
really sluggish and CPU monitoring widgets quite soon revealed - the
problem is in XCode itself - it constantly hogs CPU at 100%. In order
to simplify things up I created an extremely stupid loop - here it is
int i,c;
for(i=0,c=0;i<999;i++)
{
c++;
}
The main idea of this loop is to press Step Over around 2 times in a
second and watch CPU load. On XCode 2.5 it's ~ 5-10% on one of the
cores ( MacBook 2,1 XCode 2.5, Tiger 10.4.11) on Leopard (iMac 2Ghz,
latest fixes, XCode 3.0) it's solid 100% on one of the cores and
overall quite a bit more sluggish than on 2.5.
Can anyone confirm this issue with XCode and debugger - I have
sometimes to 'work' in debugger for hours and it's responsiveness is
important for me. May be it is XCode internal garbage collection?
Best regards,
Platon
