How Edge Computing Changes Website Performance

Traditional web infrastructure runs in one or a few data centers. Every user request travels to that data center, gets processed, and the response travels back. For a user in Singapore hitting a server in Virginia, that round trip is 200-300ms just for the physics.

What edge computing changes

Edge computing distributes compute to dozens or hundreds of locations globally. Logic runs at the node closest to the user. For read-heavy operations (content serving, authentication checks, WAF evaluation), this cuts latency by an order of magnitude.

Performance impact

• TLS handshake: terminates at the nearest edge node, not across the globe.
• Cache hits: static content is served from local storage, not streamed from a central origin.
• Security checks: WAF rules and rate limit evaluations run at the edge, adding near-zero latency.
• Dynamic content: full edge compute lets you run serverless functions at the edge, personalizing content without hitting a central origin.

Security at the edge

Moving security enforcement to the edge means attack traffic is stopped geographically close to where it originates, before it can accumulate across a long network path to your origin. This is especially important for volumetric attacks.
