Hello everyone, I'm just curious, has there been any special focus on performance improvements in the 64-bit version compared to 32-bit?
I'm asking because I recently upgraded from 32-bit to 64-bit Cygwin, and I noticed that my bash prompt would show up noticeably quicker when I opened a new Cygwin shell (I have a rather complicated ~/.profile script, so the delay is actually visible to the eye). At first I thought it was just some sort of placebo effect and I was imagining it, but the effect seemed so persistent that I just had to perform some measurements. What I found was that under 32-bit Cygwin my ~/.profile script is executed in 507ms (average of 30 runs), but under 64-bit Cygwin the exact same script gets executed in 376ms (again, 30-run average). Both measurements were done on the same machine with 32-bit and 64-bit Cygwin installed side by side (both freshly updated to their latest respective versions). That's a whopping 33% performance improvement! So I was just curious if anyone had any speculations on what exactly might have caused this performance increase. :) In any case, kudos to the Cygwin developers, great job on the 64-bit build! -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
