Hello John, JL> Are there any tips for optimizing the perf of the ruby debugger?I use: JL> ruby -r debug -rubygems foo.rb JL> Thanks JL> -John JL> http://www.iunknown.com There is no real chance for the ruby debugger. But you can try the debugger in arachno ruby (http://www.ruby-ide.com). This is implemented by patching the core interpreter and on heavy ruby intensive tasks is upto 10x faster. Arachno has two modes, a "quick debugger mode" where only the toplevel stack frame (with the local variables) are shown, this mode gives you the 10x performance increase and a slower mode which is about 5x faster. -- Best regards, emailto: scholz at scriptolutions dot com Lothar Scholz http://www.ruby-ide.com CTO Scriptolutions Ruby, PHP, Python IDE 's
