Anyone else notice chef 10.12 release being significantly slow just on  
startup compared to 10.10?

Who built the packages? Are they installed with Opscode's Omnibus installer?

Most of the 10.12.0 packages were built with the new ruby omnibus  
project whereas 0.10.10 was mostly the clojure omnibus project, so  
there could be significant differences there.

Yes, as of the last couple of revs I've noticed terrible startup times on  
omnibus on ubuntu ec2 instances, typically around 45 seconds before seeing  
the version banner. I tried an m1.large and got 22 seconds before the  
banner. I took to running class by having folks daemonize it and send  
SIGUSR1s to kick off a run. I haven't had time to trace it yet, sorry.

Sorry about that. I forgot to mention these are omnibus installer  
installations. Wow, what a difference then between the two projects, a  
7.5x increase in just the initial startup time.

Ruby 1.9.2 can, in some cases, have pathological Kernel#require performance.

Ruby 1.9.3 with the patch by Sokolov Yura (@funny-falcon) seems to perform  
much better.

Cheers,  
Jay
