Re: Upgrading 32-bit to 64-bit


I am planning to buy a new VPS from DigitalOcean. The following is the configuration:

KVM Virtualization, 512MB , 1 CORE CPU, 20GB SSD Disk, 1TB Transfer, Debian 7.0.

Digital Ocean said that I can install 64-bit Debian in this VPS. But what do you suggest in the case of a VPS ?

No, I have only 2 gig.
With only 2G of ram there is no significant advantage to you to be
running a 64-bit system.  Think about it again when you have 8G of ram.

Why?  What benefit do you expect from it being a 64-bit system?
Now I have to upgrade from Squeeze to Wheezy anyway. So I was
thinking why can't I go for a Wheezy 64-bit.
There is no significant benefit for a 64-bit system with 2G of ram.
There may even be disadvantages due to the increased memory use of
64-bit programs.  (Pointers to data are all twice as large.  Many
64-bit programs use more memory than their 32-bit programs.)

With only 2G of memory I would stick with a 32-bit system.
