Network bandwidth monitors are a dime-a-dozen at the console in Linux. More rare is an I/O transfer monitor, but they exist.
Did you know there was a memory bandwidth monitor for the console?
mbw is difficult to pin down — the home page was unresponsive for me today — but it’s out there, and it works great.
As you can see, it’s a tiny little tool that as a few options for memory tests, and reports the average bandwidth on your host. Nice and simple.
I saw no AUR package for this (which surprised me), but seeing as the home page couldn’t be reached I just stole the source from Debian and it built without error.
The host machine there is a Thinkpad X61, by the way. This machine tested at less than a tenth of those speeds. This is definitely an interesting tool to watch. … 😐
