[Ethereum] Parity warp syncing slow

This is the first time I try to install an Ethereum client and I'm trying with Parity v1.6.6 on Arch Linux (sudo pacman -S parity).

I read that the –warp option allows to save time not syncing the whole blockchain but honestly it seems still slow for my expectations…

I'm running it from 30 minutes and it's syncing snapshot 1/158, is it normal?

Just few minutes ago it re-started from zero:

concernes me, is this about some request from the Parity UI?
