Feature request: Reduce Memory usage

[josearodrigueze]

What's the feature 🧐

I don't know if I should classify it as a bug, but I want to understand why this process consumes so much memory?

Compared to other images that offer something similar, the amount of memory that gluetun consumes is 10x, for example, just by having the project running, approximately 400 MB is used, which cannot be explained if we use alpine.

In the image that I upload, of course I use my local computer but when using this in a cloud environment like Amazon, undoubtedly that amount of consumption makes it unfeasible to use this project.

Having said the above, how can I contribute to help reduce this excessive amount of consumption?

Likewise, thank you for receiving my comment.

It's the Unbound list of domains to block 😉 You can set BLOCK_MALICIOUS=off and it should drop by ~300MB 😉 Maybe worth considering changing to off by default, although it's a nice thing to have I guess.
Also soon ™️ we'll migrate to https://github.com/qdm12/dns/tree/v2.0.0-beta and leave Unbound, and its blocking consumes around ~100MB of memory instead of ~300 so that should help. Let's keep this opened.

Using BLOCK_MALICIOUS=on, memory usage went from 550MB on v3.39 to 195MB on the latest image, thanks for #137 being finally merged. I will eventually work on making this even better at a later time.

Wow, that's a huge change considering a memory saving of around 60%. I'm going to try it. Thank you very much.
