I am now working on performance tuning. I am still a newbie thus I am
not talking about "full blown performance tuning". What I do now is
just tracking my development.log to find whether I accidentally make
redundant queries because of my misunderstanding of ActiveRecord,
redundant AJAX calls, or logical mistakes.
1. From what I understand the standard log_level for development is
:debug. Are there more settings to make the development.log more
2. How can I tell what methods (and if available at what line number)
issue commands to DB?
3. Is there any tools which can help my activity?
Thanks in advance,
