Slow server start up.

[13:46:51 INFO]: [ImageMaps] Enabling ImageMaps v1.0.5 [13:51:49 INFO]: [NoteBlockAPI] Enabling NoteBlockAPI v1.6.1-SNAPSHOT

ImageMaps takes 7+ minutes to enable! Totally my server need 10 minutes to starts(with ImageMaps). 70% eats time of start up server. Server using 470 build PaperMC. And have 38 plugins.

How many images do you have? What kind of storage do you use (HDD/SSD/NVMe)?

[goosesima]

I have totally 50 images (~17,5 Megabytes) I uploaded my maps.yml to PasteBin: https://pastebin.com/raw/vW0vN6pF

[SydMontague]

My server has a comparable number of maps and images and the plugin takes <1s to start on an NVMe drive.

However, I notice most of your images are scaled, which could cause some extra computation being done at startup. I strongly recommend against using the built-in scaling where it can be avoided, since quality will suffer from it.

[goosesima]

Can you please add like config parameter what scaling to lower(to Map resolution) automatically if it prevent long loading.

[SydMontague]

You still haven't answered my question about the storage medium your server is running on. While we're at it, the CPU used is probably useful as well.

[goosesima]

I'm using Google Drive mounted to folder. Folder contains plugins, server core, everything what need for server. But for example worlds chunks load have not take many time.

Please try how long the server takes to boot with all the files in local storage. Running a server via a network mounted folder sounds like a terrible idea performance wise.

[goosesima]

I don't know but when I downloaded server to my PC and start up, console says Image file stalker not found. Removing map!, there is many messages said this. But in folder '\plugins\ImageMaps\images' is many images. See part of console output: https://pastebin.com/raw/eVqJzmVn

[SydMontague]

It either fails to read the images or it can't find them. Do they use mixed case letters? Can you place them when ingame?

[goosesima]

Some of them use mixed case letters. I can place images, but stalker doesn't work but stalker.jpg works. Other images also works.

[goosesima]

40s minutes takes to run on HDD.

[SydMontague]

40s sounds a lot more sensible and supports my suspicion that it's your Google Drive setup that causes the long loads.

You might want to store the data locally on your server instead and then just sync it with the Google Drive. Accessing files via the Internet is really slow in computer terms and the plugin has access quite a few on startup—which adds up.

[goosesima]

Okay, I will try directly from hard drive. Can you please add support for languages files for plugin?
