Delayed vehicle spawn on higher population servers

[WhereiamL]

Summary

Delayed vehicle spawn on higher population servers

Reproduction

When the server population increases, there's a noticeable delay when spawning vehicles through purchasing or using the /car command. Additionally, players sometimes don't receive vehicle keys after spawning.

Expected behavior

Vehicle should spawn instantly when already downloaded / cached into the players files.

Actual behavior

Vehicles take longer to spawn when more players are online
Key distribution is inconsistent, sometimes not occurring at all
The issue persists even with pre-downloaded vehicles (not related to vehicle streaming)

This issue only occurs with higher server population
The vehicles being spawned are already downloaded/cached (not new additions)

Additional context

No response

Current Version

v.1.22.5

Custom Resources

none

Unsure if related but I've also noticed during times with higher population that I will have vehicles spawned using the core function duplicate. Trying to pull a vehicle out of garage (with qbx_garages) will spawn 2+ fully customized as they should be but still throw a server error for too many attempts.

Happens as well for me

I have noticed the same issues with the delay and key issues. Seems after the server gets enough people the core's vehicle spawn just bogs completely down. Hope this is addressed soon!

500+ players ? maybe i got too

+1 same issue happens

I've noticed vehicle spawn times are inconsistent, especially with 30+ players. Most spawns take 1-2 seconds, but sometimes, a single spawn takes 40+ seconds. The issue happens with both vanilla and addon vehicles and seems to get worse as server load increases.

The MySQL query is fast (~2-3ms), so the delay is likely in qbx.spawnVehicle(), possibly due to network ownership transfer or entity sync issues. Occasionally, multiple vehicles spawn instead of one. Still investigating.

I'm hoping this will speed things up a bit.

We recently switched our VPS hosting from an AMD EPYC processor to an AMD Ryzen 7 PRO 8700GE, and the issue completely disappeared. It turns out the problem was related to multi-threading, as FiveM artifacts rely heavily on single-threaded performance rather than multi-core efficiency.

@iLeaksy i think it has nothing to do with machine hw this is what i am running atm, default qbx base no external scripts or anything added just plain vanilla and happens when population increases. Tested with 30+ people , randomly happens cant replicate what might be causing it , no network sync issues on fx, no hitch warnings server is only used for FXserver.

@krasher023 Hmm... I removed a bunch of the code, and sometimes it worked fine, but other times it still spawned multiple vehicles - usually three or more.

Since we're on similar VPS setups, I think what’s happening is that when a player triggers the vehicle spawn event, it waits about a second to assign ownership. If something goes wrong during that process, or if the while attempts < 3 loop is acting up it might still go through all the steps, hit a weird issue, and then end up spawning an additional vehicle.

For me, it usually spawns three at a time, but if someone spams the button, it can go up to four or even seven. I’ve been running it in debug mode the whole time, and since upgrading my VPS hardware, I haven’t run into the issue. But honestly, it might just be placebo.

Once I disabled the backwards compatibility/bridge for qbx_vehiclekeys and after I replaced all occurrences of handling vehicle keys in the "old" way, the issue was completely gone... No delays for a month now 😄
