How can I improve the performance of OpenBSD?

So, I installed OpenBSD on my ThinkPad T400 a few weeks ago. It was going okay, but then a job came up that required Windows.

I do not run Windows on any of my devices due to a galaxy of reasons, but i keep an old hard drive handy with Tiny10 that I can shove into a laptop when needed (a rare occurrence).

Anyway, I noticed that somehow, Tiny10 actually ran considerably better than OpenBSD on this particular machine, despite also using a hard drive rather than an SSD.

My OpenBSD setup uses bspwm, and my RAM usage is normally quite low unless vimb is open.

Is there any way i could increase the performance of OpenBSD on my ThinkPad?
