See comments below. The hardware is ancient. I'd say try running chrome on windows on this hardware and you'll probably see it's also horrible. "minimum hardware to allow using chromium with no delays" is probably a machine with a fast nvme drive, 8+ cores, and 16+ gb ram. > I know, it should be advisable to get the maximum performance > hardware, but i'm not in that case. > > OpenBSD 7.1-current (GENERIC.MP) #483: Sat Apr 23 05:33:19 MDT 2022 > [email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP > real mem = 7711170560 (7353MB) > avail mem = 7460139008 (7114MB) > random: good seed from bootblocks > mpath0 at root > scsibus0 at mpath0: 256 targets > mainbus0 at root > bios0 at mainbus0: SMBIOS rev. 2.7 @ 0xe86ed (64 entries) > bios0: vendor Hewlett-Packard version "K06 v02.77" date 03/22/2018 > bios0: Hewlett-Packard HP Compaq Pro 6305 SFF This is an almost 9 year old machine.
