ThatвЂ™s probably because vagrant ssh-config takes most of that time to sort things out: % time vagrant ssh-config > /dev/nullДў,53s user 0,79s system 77% cpu 4,269 total Vagrant ssh is slow to connect % time vagrant ssh -c whoamiДў,57s user 0,73s system 82% cpu 3,984 total This is especially annoying when running single spec which should be fast. The problem is that every time I start rspec, it takes a few seconds to connect to the box, before actually doing anything. I use RubyMine and Vagrant for my Rails development and run RSpec specs from RubyMine for convenience. (DonвЂ™t ask me why JetBrains thinks this is necessary.) Increasing this limit affects, among other things, the Inspections performance too as these are run for all tabs after every spec run. RubyMine has default setting of allowing only a handful of tabs open at the same time. Now, after running specs, RubyMine CPU usage jumps to around 100 % for only a little while and then returns to normal. In my case there were a lot of вЂњDouble quotesвЂќ as well as whitespace whitespace warnings, but growing tired of not finding any low hanging fruits, I decided to just disable almost all warnings and left only error-level Inspections.

Unfortunately RubyMine does not tell you which Inspection it currently runs, so it is trial and error to find out what causes the slowness. Navigate to Preferences > Editor > InspectionsВ and go through the long list.

One support ticket for WebStorm though tipped me off and turned out that the culprit are Inspections вЂ“ those little yellow or red markers around right gutter that tell you when your code smells or is outright broken. I even tried profiling the app to see if it gives any ideas (hint: it did not). Googling around for solution did not find anything, especially as there are not background processes running. If I do fast iteration on specs, then this high CPU usage is constant and heats up my Mac, causing fan noise and of course drains battery. Instead, set a breakpoint, start the debugger, examine some objects, and slowly step through your problems.RubyMine, being an IDE and not light editor, is expected to hog some CPU.В But after each RSpec run, the CPU usage jumps to 300 % for several minutes. DonвЂ™t litter your code with Kernel#puts and friends. If youвЂ™re using an IDE, take time to learn its debugger. Use your cursor as a temporary breakpoint with alt/option + F9. Instead of using the Debug tool window, examine a variable inline by placing your cursor on it and pressing command + alt/option + F8. Use alt/option + F8 to evaluate arbitrary expressions. Use command + N in the Debug tool windowвЂ™s Watches pane to watch a specific variable. View recent debug sessions with control + alt/option + D.Д®xamine variables in the Debug tool windowвЂ™s variables pane.

Use control + D to re-run the last debug session.

This will automatically open the Debug tool window ( command + 5). View existing breakpoints with command + shift + F8.Дebug the current program with control + shift + D. In this post, weвЂ™ll look at debugging in RubyMine on OS X.ДЄdd or remove breakpoints with command + F8. I still donвЂ™t enjoy debugging, but RubyMine has made it much less painful.

RubyMine includes a standard debugger that has minimal setup and works out of the box. Ugh, typoвЂ¦Дebugging like this isnвЂ™t fun especially when pairing. Let me add a few Kernel#puts calls to see whatвЂ™s going on. Before using RubyMine, my debugging workflow went something like this:
