One CPU is maxed to 100% when forking. This speed explained why opening bash took as long as 10 seconds, and I wanted to find out why it was so slow. Is it possible to profile the implementation easily? -- View this message in context: http://www.nabble.com/Slow-fork-issue---Win-x64-tp19538601p21561482.html Sent from the Cygwin list mailing list archive at Nabble.com. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
