vvis.exe freezing?

Edit: nvm
What can cause vvis.exe running really slow, basically freezing or crashing?

optimization
this site delves into the subject quite well, even though its kinda dull to read
http://www.student.ru.nl/rvanhoorn/optimization.php?chapter=intro

this guide helped me a bit
http://developer.valvesoftware.com/wiki/Controlling_Geometry_Visibility_and_Compile_Times

and there are a few guides on optimization in the tutorials section of this site

as a quick guide:
change smallish and oddly shaped brushes to func_details (select brush and press ctrl t, then choose func_detail from the drop down menu)
texture the unseen sides of brushes with no draw (use face edit tool)
look into hints and area portals
beware of large open spaces
and finally, if your map is still at an early stage and this is sounding overwhelming, then you can set vvis to fast and continue working on your map with little delay

though be warned there is always a chance it could be something else

and all my brushes ARE func_detail.

Could be that. Make sure non are touching the void outside your skybox.

Also make sure you have no props or light in the void.

Post your .Vmf for a quick look as to why or hop in steam chat room we can look at it asap =)

Learn from my mistake, never make large relatively open areas with lots of details.... last vvis- 41 hours(after extensive optimization). /facepalm. Of course updating my eight year old computer might help too. >.>

Holy crap... 41 hours?

Something more interesting to read than that other link (when I read it, I just wanted to throw my computer out the window...) http://forums.tf2maps.net/showthread.php?t=1560
