[bitfolk] 64 or 32 bits?

Hello BitFolk People

I'm about to install Debian on my shiny new SSD-based BitFolk VPS, in the standard configuration with 1GB of RAM and 10GB of disk space.

And the first question is: Should I, in 2015, go for 64 bits or 32 bits?

* The BitFolk rescue environment supports 64 bits now.
* Addressing 1GB of RAM is not an issue.
* Will a 64-bit system run faster? Or slower?
* Will 64-bit executables waste precious disk space?

For a long time, running 64-bit systems involved various hacks and workarounds and 32-bit libraries for software that was not yet compiled for 64 bits. Is the opposite happening yet? -- i.e. is it becoming necessary to allow for software that no longer supports 32 bits?

Any suggestions and advice will be appreciated.

Cheers,

Chris
