Zypper Slow Download Speed in Tumbleweed

Hello everyone. Days ago I moved to openSUSE Tumbleweed from Fedora 25. And Tumbleweed has already become my favorite distro. But zypper is very slow.
It takes forever to update Tumbleweed through zypper and Yast. In Fedora, the update used to download at 1.3 MiB/ps but in Tumbleweed the highest download speed I reached is 270 KiB/ps. I think part of the problem is that I have no Tumbleweed mirrors near my country. But can I increase the speed even a little by tweaking zypper? I don’t want to move to any other distro (Don’t want to move to leap cause it isn’t a rolling release distro). Tumbleweed is my favorite, but the download speed is killing the rolling release experience.

I have 4 GB ram and a decent CPU. Please help. :’(:’(:’(
