I just thought I'd share my zerolink experience with the list, since
a search of the archives for "zerolink performance" doesn't bring
anything relevant up. It seems that turning off zerolink can have a
massive effect on the debugger's performance.
I'm working on a medium-sized C++ app with a release binary about
1.5MB in size, and about 100 source files. I've been debugging with
zerolink enabled, and have been getting extremely frustrated with the
debugger (20s to stop at a breakpoint, 2s for each single-step within
a function on a 2GHz G5 iMac). I finally got round to raising this as
a bug (radar://4349128) and was asked to turn on Xcode GDB logging.
This suggested that zerolink was the main problem, which hadn't
really occurred to me, since it's claimed to _speed_up_ the
development cycle(!). Anyway, performance with zerolink disabled was
about 5s to stop at the first breakpoint, and just under 1s for each
single-step. Still not ideal, but a vast improvement.
Maybe this is something everyone else already knows, but I thought
I'd post it to the list as I didn't see anything in the archives.
