Why does Tor run so slow?
Why is the Tor Browser so slow? The Tor Browser is slow* because it routes data via three relays (servers) for your privacy. Regular connection, on the other hand, just connects you straight to the website/service, making it much faster.
Do bridges make Tor faster?
Using bridges in combination with pluggable transports helps to conceal the fact that you are using Tor, but may slow down the connection compared to using ordinary Tor relays.
Do I still need a VPN if I use Tor?
A VPN isn't a requirement to use Tor, but it helps a lot. It encrypts your whole traffic, masking it from the ISP. In short, it's much safer to use Tor with a VPN. Not all VPNs offer Tor features in their product.
