Extremely bad performance on VirtualBox VM

I read on Twitter you’re back up to 25k tps on an old laptop. Awesome! If there was something you did for tweaking and performance tuning, would love to hear it. Meanwhile, have a great weekend!

Edit: Whoops! Now I understand your 25k tps was on a separate box, not the VM you were running. So, still an open issue.

Q: I understand you’re running Ubuntu in the Virtual Box. What’s the native OS on the box you’re running the VM?
