I've read the MongoDB documentation, and it comes with a warning about 32-bit systems; particularly that they're capped at 2 GB of available RAM for Mongo.
So I was wondering if that statement meant anything in regards in running MongoDB in a low memory setting like Linode's 512mb of RAM based VPS. I doubt it matters but with a 64-bit distro for later resource adding.
Any warnings or would someone recommend a minimum of a RAM to choose in a VPS for MongoDB? I know project requirements figure into this, but I mean minimum in the sense of what'd be laughable to do without for even spinning MongoDB up.
