I\'m planning to build a website that will be a simple CMS where users submit and view postings with videos, photos and text.
One decision I want to make is choosing
my suggestion is to go for 1.9.2 if possible because 1.9.2 is much faster than REE and MRI 1.8.7. However bear in mind that 1.9.2 like its MRI 1.8.7 is not a full optimized version, so you would expect to see more RAM eaten up compared to REE. If you could not upgrade to 1.9.2 yet, I'd recommend you to stick with REE.
Update: REE has just merged all changes from MRI 1.8.7-p334, so it's good and hot ;)
