Re: The New GNUstep Seems Slow

[Fred Kiefr]

I don't know about any specific reason why GNUstep should now be slower. This 
seems to be an important issue to investigate. Which bacend are you using? A 
wrong backend is the most common reason for a slowdown. If this isn't the case 
we need to use tools to find out where the time gets spend. I will send a mail 
on this next week, when I am back home.
