Maps in game client are not cached?

[Gilbertus]

I recently making some maps of my surroundings. The map sever is very laggy and its a bit painful. Almost all the time my local and regional maps stays blank and even GUI mini map have holes and not refreshing images.
From what I see all maps are downloaded every time I open map (local, regional) or go to some part of world (GUI map). Am I right?
If that's true its the main reason for map server overload.
EDIT:
Hm. Maybe they are cached but cleared when changing "zones". When i walked into house and get back local map was starting to load again.

Not quite -- they are redownloaded whenever the garbage collector frees them.

I would like to cache them, indeed; and I did try once, but it turns out that (at least Sun's implementation of) the JNLP caching mechanism is tremendously, unthinkably slow, so the caching of maps actually bogged down client performance.

If that's true its the main reason for map server overload.

Nope. HTTP traffic, in total, takes no more than 20% of the server's bandwidth, and map downloads are obviously just a still smaller part of that.

Thanks for answer.

Unfortunately I don't talk in JAVA. Can this bloody garbage collector be prevented from freeing those precious data for whole client session?
Or at last give him log delay before he touch them. Maps don't change often.

Good to know.
Wonder why my maps are loading so slow then. I don't think its my connection i seen some topics about not loading maps on forum.
But it seem its not server problem either.

EDIT:
I do have problem with forum too. I try to edit this post and it took me like 30 min to open edit page.
I did traceroute and this what i get:

It can; but right now only at the cost of keeping all the maps in RAM. I don't really know how big a deal that would be, but I'd imagine it might use quite a bit too much memory for people exploring or otherwise walking around a lot, at least.

Wonder why my maps are loading so slow then. I don't think its my connection i seen some topics about not loading maps on forum.

I don't know exactly why, but for some reason, it seems that TCP traffic suffers much worse from the congestion than does the game protocol.
