Had any one run into performance issues after upgrading to ruby 1.9.3. My application was working fine until it was on REE but after up gradation it seems to be too slow. One of the reasons could be Garbage collection with ruby, having said that i don''t have much idea on how to tune it. It might not be the only thing that caused the performance issue but i think that is a significant change between REE and 1.9.3. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Assuming you''re using Rails? - Are you seeing the problem in development mode or production mode? - What leads to to believe garbage collection has anything to do with your problem? - Have you collected performance metrics that lead you to suspect the GC? Generally speaking Ruby 1.9.3 is significantly faster than Ruby 1.8.x, including REE. I also really doubt the garbage collector has anything to do with your problem. Whenever I hear about noticeable performance drops after an upgrade it generally leads back to something basic, like the OS. For example I, as do many others, recommend running Ruby on some form of UNIX based OS (BSD, Linux, Mac, etc.). -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

@robert
OS is Linux,
Ruby 1.9.3-p194,
rails 3.2.6
It is slow in development as well. The slowness is in reporting
module, where a report is having large no of records. one interesting
thing is the reports are pretty fast on 1.9.3-p0.
