Another one guide for noobs like myself. This was the biggest problem
I ran into while playing with OpenBSD. My browser was laggy and
randomly crashing under higher loads with many tabs. So I googled
and have found an answer here:
http://undeadly.org/cgi?action=article&sid=20070508003748&mode=flatBut that answer is not very noob friendly. So I have decided to simplify it.

So you need to edit /etc/login.conf
#nano /etc/login.conf
# $OpenBSD: login.conf,v 1.4 2015/02/17 10:18:36 sthen Exp $
#
# Sample login.conf file. See login.conf(5) for details.
#
#
# Standard authentication styles:
#
# passwd Use only the local password file
# chpass Do not authenticate, but change users password (change
# the YP password if the user has one, else change the
# local password)
# lchpass Do not login; change user's local password instead
# radius Use radius authentication
# reject Use rejected authentication
# skey Use S/Key authentication
# activ ActivCard X9.9 token authentication
# crypto CRYPTOCard X9.9 token authentication
# snk Digital Pathways SecureNet Key authentication
# tis TIS Firewall Toolkit authentication
# token Generic X9.9 token authentication
# yubikey YubiKey authentication
#
# Default allowed authentication styles
auth-defaults:auth=passwd,skey:
# Default allowed authentication styles for authentication type ftp
auth-ftp-defaults:auth-ftp=passwd:
#
# The default values
# To alter the default authentication types change the line:
# :tc=auth-defaults:\
# to be read something like: (enables passwd, "myauth", and activ)
# :auth=passwd,myauth,activ:\
# Any value changed in the daemon class should be reset in default
# class.
#
default:\
:path=/usr/bin /bin /usr/sbin /sbin /usr/X11R6/bin /usr/local/bin /usr/local/sbin:\
:umask=022:\

Only interesting part for you is(NOTICE VALUES IN THIS EXAMPLE ARE ALREADY INCREASED):
default:\
:path=/usr/bin /bin /usr/sbin /sbin /usr/X11R6/bin /usr/local/bin /usr/local/sbin:\
:umask=022:\
:datasize-max=2048M:\
:datasize-cur=1536M:\
:maxproc-max=512:\
:maxproc-cur=256:\
:openfiles-cur=1536:\
:stacksize-cur=4M:\
:localcipher=blowfish,8:\
:ypcipher=old:\
:tc=auth-defaults:\
:tc=auth-ftp-defaults:
After this little tweak your browser gonna be rock solid. Of course you can make
values even higher. And my laptop produces less heat after this.
