Link? :)

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

That ThinkPad T400 is REALLY old and OpenBSD is known to be slow - so if you connect slow hardware with slow OS ... you get what You get.

IMHO update to at least to T420/T430 ... or change OpenBSD to NetBSD or FreeBSD.

About my other comment below/above - its already fixed in latest version of pkgbasify(8) so you can convert Jails to PKGBASE if needed with that tool.

Currently pkgbasify(8) does not work inside Jails - I created a BUG here:

Are you not using the W520 anymore? Your posts were very useful in configuring mine.

I wally like W520 - but it has one drawback for me - it needs at least 135W PSU - which means I can not use USB-C adapters ... but the thing I need the most from W520 (comparing to T520) is that quad core CPU ... and I just bought T520 with quad core CPU - unfortunatelly also with Nvidia 4200 card ... but I will seek for one with 'only Intel GPU'.

The two W520 I have - I will clean them up and sell some time.

So for TL;DR - I will replace mine W520 with T520 to have it as a backup :)
