BTW I am limited by internet. RAM (8gb) should not be an issue because Bitcoin core is the only thing that is running on my device. Nothing else on the foreground or background as you can see on the screenshot (only 50% ram occupied).
Just checked your graph. It seems progress decreased as you got closer to sync. Another user said the same thing.
Keep an eye on your
chainstate directory. Once that grows, your RAM won't be sufficient anymore.
