[Swarm-Support] Optimization with Shark

[Gary McKeown]

Hello all,

As swarm on OS X is getting some attention now I thought I would mention 
using Shark to optimize apps, it is part of the CHUD tools.

If you have the dev tools installed, as you surely must, then Shark is in 
/Developer/Applications/Performance Tools/Shark.app

a guide on how to optimize a Cocoa GUI app can be seen here:
http://developer.apple.com/tools/sharkoptimize.html

and here is my short users guide:

close other programs open Shark run yourSwarmApp as normal choose Time 
Profile in the first pop-up button (its the default) choose process in the 
second pop-up button choose the yourSwarmApp in the third process pop-up 
button click the start button after ten seconds or so click stop click on 
the high percentages in the results window to see where your app spends 
most of its time.

without a good Xcode integration there will be no direct linkback to the 
source code from Shark but I have found it very useful to show where my 
apps spend most of their time.
