Dear Gentlemen
I use XCode document viewer quite a lot to browse documents and search
API and stuff. Unfortunately in XCode 3.x it is very slow when
scrolling the document or results list view. The problem is simple
just open any doc set, try to scroll the result set, note bad
responsiveness, then open any big document and try heavy scrolling it
with mouse scroll button - look at CPU usage at this time - here it
almost peaks (iMac7,1). Now for tricky part - if you move away from
the document viewer window and then move overlapping window in such a
way that you see document viewer and use mouse scroll it works
excellent. Also some times it works good as well right from the start
but nevertheless the scrolling in most of the cases is very jittery.
Anyone experiencing the same? It troubles me that scrolling is bad not
only in document viewer part but in list view as well. All other apps
work fine.
I've never used Instruments before (mostly 10.4 coding still) and it
was my first try - pretty neat stuff! However I am not still very good
at interpreting stuff - looks like - garbage collection is to blame??
I am posting a trace on site http://www.elverils.com/Trace.tar.bz2 -
can you please share your thoughts on this.
Thanks in advance!
Best regards,
