Try opening a few Gmail tabs on a machine that's more than a few years old or has a relatively low amount of memory. It might be an okay experience if opening Gmail is literally the only thing you're doing with the machine.

I’ve done that before, for working with multiple email accounts, and don’t remember it interfering with system memory needs.

Although google has had a huge problem with keeping accounts separate in the same browser, but that’s not a gmail thing.
