You could run that little amount of stuff on a pi zero. You're not out of RAM. You're not out of CPU. I'm guessing you're waiting for I/O unless your SD card is throwing a zillion errors and is close to failing. Check that by running 'dmesg' and looking at your syslogs. For how to debug https://bencane.com/2012/08/06/troubleshooting-high-io-wait-in-linux/ is one resource to look at.
