Where'd you read this? Longview works just fine on a 32-bit OS. I would guess at least 50% of Linode's deployments are probably 32 bit. Unless you have a good reason to run 64-bit (eg large database, Mongo, etc) 32-bit will work just fine—that's what
Linode recommends as well.
If you're worried about traffic, one thing you can do is make sure you do some basic performance tuning right off the bat. Running W3 Total Cache in WordPress makes a big difference. Also If you're going to run the usual LAMP stack, I'd recommend PHP-FPM with Apache's Worker MPM. Ever since I switched to that setup, I've noticed a nice boost in speed to my sites, especially when it comes to first byte, etc. since you're not firing up PHP every time Apache runs. (You can also do NGINX but I 'm old school when it comes to Apache.)
