Subject Re: In-browser debugging with Node.js couchjs
Date Mon, 11 Feb 2013 15:06:35 GMT
Ah, so how it works. Brilliant!

But am I right, that os_process_limit should be raised for it (long
debug - long respond time) and there would be hard to locate
bottlenecks with such technique? Probably, next evolution step should
have profiler and frames stack tracer features with some backlog for
post-analysis.
