Hey people, I''m planning to get a new notebook which will be primarily used for RoR development. I''m not sure whether to get a i5 (dual core) or i7 (quad core) cpu. I did a google search and stuff and couldn''t really find any benchmarks or something like that about multi core support of Ruby/RoR. Does anyone know soemthing about it? Btw. I''m running quite cpu demanding scripts that take up to 30 minutes to run pretty often, that''s why I need to know if a i7 would get the job faster done than a i5 cpu. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

If you are doing development on a single machine it is not just a issue of Ruby being able to take advantage of the cores but the other applications that you will be running. The database, the editor, the OS itself. They all need CPU. If the system is swapping things in and out because you don''t have enough RAM then the number of cores you have becomes a non issue. So cores, the more the better. Ram, the more the better. The question is how much can you get away with (unless you have very deep pockets). I used to do Rails development on a Macintosh 12 inch G4 Powerbook with 1Gb of ram running OSX, PostgreSQL and Textmate. Why do these scripts take a long time to run? What is your CPU usage when they run, how about disk / network usage? Page swaps? Find out where the bottleneck on your scripts is and that should give you some idea what resource needs to be boosted (at least for your existing configuration). -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Well, at the moment I''m on a Core2Duo and 3GB of RAM. CPU usage is ~90% and RAM alltogether 2.0 - 2.5 GB used. I''m planning to go on 6 or even 8 GB the only question remaining is whether it''s gonna be a i5 or a i7. -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I had an i7 mbp. I just bought a mbair and due to the fact that it uses flash media for storage it feels about a third faster at most rails dev tasks I throw at it. For instance my cucumber suites run about a third faster than my i7! Even parallels starts up and shuts down faster. Working on large Photoshop files has the i7 leading. But that''s a small part of my usual workflow. I''m loving the new mbair by a long shot.
