Coop join performance

[BrightCandle]

Statement of the issue

We recently setup a Dedicated server for coop missions for our group based on Pat Wilsons Combat Generator. It is producing missions about 12 MB big or so. Performance in loading the missions is pretty poor. PWCG takes a while to generate, the dedicated server takes a really long time to finish loading the mission and register on the master list and then every client takes many minutes to load into the slot up screen. The combination of these 3 together must be nearly 20 minutes or so. When we were doing this without a dedicated server  the creation of the server and joining were considerably faster.

 

Reproduction steps

1. Generate mission with PWCG.

2. Start the dedicated server with the SDS containing that mission.

3. All players join the server once it appears.

 

Without a dedicated server 1. was slow but 2 and 3 were seconds to a minute. With a dedicated server 2 and 3 take 15x as long.

 

Am I missing some setup parameter magic here? I increased the bandwidth in the startup.cfg but that doesn't seem to have done much, nor the bandwidth values in the SDS setup and I am running the machine on high performance. It isn't the quickest of boxes, just  a 3930k but at the same time it runs the game well it just doesn't load very quick and even doubling the CPU performance I don't think is likely to solve the extent of the weird problem we are seeing unless its instruction based perhaps?

 

I have attached the mission.sds (censored). But if there is something else I should be changing to improve the mission load and/or joining performance to give me something a bit more like the client join experience please let me know.

Use either resaver.exe or mission editor to save the mission to msnbin format, and then rename the original .mission file so that the server will load the msnbin file.

Oh wow that is a major performance uplift nice one thanks so much.

 

I need to request an update to PWCG to delete that mission file as an option because that is a big deal.
