Extremely slow app update through zappa update --all

[nyxdata]

I've built a small serverless application about ~10mo.

When I use the command zappa update, it takes at least 10 minutes before the beginning of the update.

I use windows and the following settings:

{
"dev": {
"app_function": "app.app",
"aws_region": "eu-west-1",
"profile_name": "user",
"project_name": "nyx",
"runtime": "python3.8",
"s3_bucket": "zappa-nyw",
"memory_size": 2048
}
}

I've tried to add exclusion exceptions to get it faster but nothing has changed.

Thank you for your help.

Windows deployment and updates are 5-15x slower on Windows than on Linux and macOS unfortunately. Zappa was developed on a mac and works best on UNIX-based.

I tried debugging it when I was on Windows, but it was a problem with a recursive function which goes through the folders of the project and it was not easy to pin-point the problem

Before I changed to mac, I was using WSL2 to "bypass" that issue, which I recommend you using too

I'm on ubuntu, zappa is also running extremely slow on my laptop , and it used to be very fast, it uses 100% CPU

$ zappa -v

Hi @Techget
You need to provide your zappa_settings.json file and requirements.txt file in order for us to pinpoint the issue.

So, you have only one region deployment or multiple region deployments?
If it's only one then I would look into the internet connection and the place from where you're trying to deploy.

[Techget]

Deploying to single region and the network speed is okay with ~5 MB/s.

It often stucks at a stage for quite while e.g. Packaging project as gzipped tarball.

[souravjamwal77]

Here is what I would do:-

1. Check uplink/upload speed
2. The place you live in and the region you're uploading to (there could be latency issue, if there is any package check is happening then I think it has to make 2 zips and 2 seperate uploads. Read this Article
3. If you're using a mobile hotspot even on a 4g network then still the uploads will be slow and slim handler may also be slow to package the packages.

Let me know what worked for you. I will try to replicate your setup.
