Given that slack is irc++, I’d like to see a comparison with something like pidgin connecting to a slack channel too. How much memory does that use?
Colloquy launches one process and weighs in at 70MB, thereabouts. When in the background, it mostly idles at 0% CPU utilization.
Because I am old, I think 70MB is way too much memory for an IRC app to use, but compared to Slack, it’s a drop in the bucket.
I’m using WeeChat with the wee-slack plugin, and the whole process tree is using about 77MB of resident memory. That includes a bunch of IRC connections and several other plugins, though (which translates to at least one instance each of Python and Perl).
It’s not particularly impressive, but it’s at least reasonable on a modern machine.
