When the server comes across maps containing large amounts of items it

metalforge.
The way I would solve this is to have the map loader count how many
objects it has loaded. After some fixed number, it would stop until the
next time tick. There would be no processing of objects, including
players, on a partially-loaded map.
This would eliminate the lag for everyone except the player entering the
cluttered map.
I'm just not sure if this is less work than the other approaches to
solving the problem that have been suggested.
the problem is that the loader itself stores state information.
So, while unlikely, you could get this case:
Player A enters some exit. Map starts to load, gets to point, and returns
expecting to continue next tick.
Player B enters map, laoder kicks in, this map finishes.
Next tick, when it tries to resume loading map A, the lex state is messed up,
so the load fails or you get weird results.
Now this can obivously be fixed (is any map in proces of being loaded but not
finished, etc).
Many years ago, I tried this approach, but never to it stable enough.
I'd still be more tempted to just go the threading approach - to cover the
above case, its probably not too far from getting a threaded system anyways.
Its how well you want a threaded server to scale that becomes an issue. One
coud just set some very broad thread locks - easier to do, but means it wouldn't
scale as well. But at a first pass, and given current loading, that may be good
enough.
