[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
