Time to compile a map

[keybounce]

In build 23783, it takes almost 2 hours for this map

Can this map be simplified a bit?

The compilation time is related to the recent changes in the tracing and routing code. It's not the map's fault.

Recently (days) I had 46 minutes compilation time on the same map with my AthlonXP 2000+ (1667Mhz) on Linux. I'm sure it isn't normal. I mentioned this to Duke he thought the problem is on my side ofc. Here is the proof he was wrong...

@geever:
Sorry for suspecting your system
Back then I didn't know that certain maps take *very* long for the lighting (ie. 'FACELIGHTS')

The routing/pathfinding code ends after the 'CONNCHECK' pass (which doesn't take toooo long here).
Lighting stuff is Mattn's business afaik.

Could you plz come up with a log of the same map-compile with current trunk code ? (ie. how long does it take *now* ?)

[Mattn]

which reminds me - i still can't use the stairs in this map (though i haven't recompiled in the last days) - would be nice if you could test that please.

Yeah, true, lighting takes much time but that's using traces no?
H*lly sh*t it's even worse now 70.5 mins...

yes - indeed - and the lightmap code hasn't changed much recently. but even if the compile time is long, it's more important to get (oe keep) the tracing in-game at a reasonable speed. but i suppose that some lightmap related tracing is broken anyway - see e.g. the bunker map - the lightmap on the lower level is totally b0rked.
