64 bits vs 32 bits on VDS/cloud for webserver?

Question

Ruby on Rails

What to choose for the server on which the rail projects will be hosted?
It seems to be 64 bits faster (is there a link to such a study?). On the other hand, 64-bit applications consume twice as much memory, and in VDS / cloud you pay for the memory.
What to choose and why?

Answer 1

Far from 2 times. Debian gets a difference of 100-200 mb with a fully occupied 1GB 64 bit system.

Answer 2

If RAM > 3 gigs - then 64 bits, otherwise 32

Answer 3

Forget about 32-bit systems already. what is 2, 3, 4, 8 gigs for a project?
RAM is a cheap resource, and there is never enough of it.
face the growth of the project (s) -> you will increase the power of the cloud -> you will face the need to redo everything according to your mind.

Answer 4

If the question is - how cheaper and in order to be of high quality - take 32. Of course, look what you will use in your rails. There are quite a few options for programs that need 64 bits to work properly. (Personally, I have only encountered the no-sql MongoDB database, where the storage size is limited to 2 GB in a 32-bit distribution)

Answer 5

I put only 32 bits, unfortunately in php frameworks and something else there is a difference what bit depth you set, in 32 one can turn into 64 another, so everything is initially 64 everywhere.
