@solderpunk@tilde.zone Thanks for your suggestions!
I tried Bombadillo and I saw a RAM usage of 477 Mo while opening gopherpedia.com (I'm doing all my tests with gopherpedia.com) and it increased to even 625 Mo just by scrolling the homepage. 😮
Then I tried Stubb and this time I saw a RAM usage of 6 Mo which is much better.
I don't know why Bombadillo takes so much RAM, maybe Go programs are like this?
I take this opportunity to tell you that I really like to read your phlog!
