I could grep the heck out of some log files on that.

  I know you're joking, but that operation is often disk-io bound, not cpu or memory bound... and the disk is still EBS, you'll not get much better performance on that than on an m5.xlarge I bet, unless you use a grep regex that needs to gobble lots of data into memory as part of the search.

    With that much memory, a ramdisk would seem completely reasonable.

    tmpfs would solve the disk-io

    It's disk-bound the first time you run grep, but the second time you run it the log file is going to be in memory, if you have enough memory.
