It depends. ? If you connect to a server of ours that is reasonably close to you, you shouldn’t see any decrease, or a tiny one. This is especially true with our speed-optimized IPsec service. Over great distances, you will likely see more of a slowdown in speed, but it shouldn’t be too noticeable in any practical terms. And, due to how the VPN “optimizes” traffic you can often see an INCREASE in speed, or general performance, with many applications.
