How to optimize objects loading - NoteND - 30.12.2018

Hey!

Thats probably my last time posting this since I dont wanna spam it really.. basically what is happening is that I'm using XML Loader to open .map file, and from that map file I'm getting object, racepickup and spawnpoint coordinates (info).. now.. racepickups and spawnpoints load fine since there arent many of them, but objects take about 10-20seconds to load which is fine, but what I do not understand is why during that time it seems like server is freezed, you can move and stuff but you cannot type anything into chat.. whatever you type will appear after objects load.. so I need help with how to optimize it so that its gonna load objects but not completely freeze the server. Thanks for help !

p.s. I use the same code(script) for loading racepickups and spawnpoints

Your server freezes because SA:MP server runs on single thread - that means it cannot run multiple blocks of code alongside each other and they are waiting "in line" to be executed. Most of the time it is not a problem as it doesn't run much demanding tasks, but parsing a big XML file can be indeed demanding.

You can try this plugin https://sampforum.blast.hk/showthread.php?tid=653097 to make the whole function run in other thread alongside your server so it will be possible for server to process player commands etc. I've never used it myself, so I don't really know if it works.

How many objects are you trying to load? Just asking from pure curiosity.

Are you using 0.3.7 or 0.3.DL?

There are on average around 4000 objects, sometimes more sometimes less

EDIT: i've tried loading 30000 objects myself once I was doing some other project, and they loaded literally in a second.. so idk whats problem here

Were you using the same loader for reading the XML file? It sounds like your .map file may be corrupted or something.
You can try using other XML loaders, maybe this one that you're using is badly optimised.

XML parsing is extremely slow if there are a lot of values. Just see how many values there are in an MTA .map file per entry, especially objects!

The meta.xml file is just a few bytes at most, that's why it is that fast.

Even a PAWN parser for MTA Maps is faster than the XML plugin, since half of the values in the XML aren't even usable in SAMP (the XML Plugin still parses them).

So what do you suggest.. I try using filemanager or something like that?
