@JustinNakamoto Tor probably no longer works in your older version, >v2.8.0 contains the supported Tor dependency.

I upgraded to 2.8.4. new blocks took awhile to download. So I uninstalled it and went to 2.7.2.

Yes, versions >2.8.X are slower to sync because they use Bitcoin's P2P network instead of a central server to download the BIP158 compact filters. More sync improvements are coming soon: 

on a side note, is it possible to use obscura (which uses a mullvad wireguard vpn) as a proxy with wasabi wallet, while other applications are not sent through obscura? can it use it with udp turned off?

Since Wasabi already uses Tor, it isn't necessary to use a VPN. I'm not sure about how to configure single applications for VPNs, that sounds like something the VPN software or your OS would handle.
