Does SSL Slow Down Your Website?

Yes, it’s true that SSL can impact the performance of your website.

But its efforts are so minor that saving a few milliseconds won’t outweigh the increased level of security that SSL affords.

With HTTP/2, HTTPS is only getting faster so any performance impact SSL adds to connections is dropping fast.

Does https make site slower?

HTTPS has encryption/decryption overhead so it will always be slightly slower. SSL termination is very CPU intensive. A more important performance difference is that an HTTPS session is ketp open while the user is connected. An HTTP ‘session’ lasts only for a single item request.

How can I speed up my SSL handshake?

2 Answers

  • Disable the Domain lookup, and allow Non-SNI to reach primary domain.
  • Instead of named hosts, use IP address for the :443 VHOST entry.
  • Cache SSL Sessions.
  • OCSP Stapling (speeds up SSL)
  • HSTS (can do preload so http:// requests become https:// requests in the browser.

How does using https affect websites compared to http?

HTTPS: Secure HyperText Transfer Protocol

In many ways, https is identical to http because it follows the same basic protocols. The http or https client, such as a Web browser, establishes a connection to a server on a standard port. However, https offers an extra layer of security because it uses SSL to move data.

Is https faster than HTTP?

HTTPS is faster than HTTP. Secure is faster. With HTTPS the browser needs to do extra work, which makes the initial request slower. Despite this, HTTPS sites (can) perform better.

Is https better than HTTP?

HTTPS is HTTP with encryption. The only difference between the two protocols is that HTTPS uses TLS (SSL) to encrypt normal HTTP requests and responses. As a result, HTTPS is far more secure than HTTP. A website that uses HTTP has http:// in its URL, while a website that uses HTTPS has https://.

Is http slow?

Slow HTTP attacks are denial-of-service (DoS) attacks in which the attacker sends HTTP requests in pieces slowly, one at a time to a Web server. If an HTTP request is not complete, or if the transfer rate is very low, the server keeps its resources busy waiting for the rest of the data.

What does TLS handshake mean?

A TLS handshake is the process that kicks off a communication session that uses TLS encryption. During a TLS handshake, the two communicating sides exchange messages to acknowledge each other, verify each other, establish the encryption algorithms they will use, and agree on session keys.

How long is SSL handshake?

This handshake will typically take between 250 milliseconds to half a second, but it can take longer. At first, a half second might not sound like a lot of time.

What is a SSL handshake?

SSL follows a handshake process that sets up a secure connection without disturbing customers’ shopping experience. The SSL handshake process is as under: Both parties agree on a single cipher suite and generate the session keys (symmetric keys) to encrypt and decrypt the information during an SSL session.

Why is http bad?

In terms of security, HTTP is completely fine when browsing the web. It only becomes an issue when you’re entering sensitive data into form fields on a website. If you’re entering sensitive data into an HTTP web page, that data is transmitted in cleartext and can be read by anyone. And those customers data is insecure.

When should you not use https?

You should use HTTPS everywhere, but you will lose the following:

  1. You should definitely not use SSL Compression or HTTP Compression over SSL, due to BREACH and CRIME attacks.
  2. One SSL cert, one IP address, unless using SNI, which doesn’t work on all browsers (old android, blackberry 6, etc).

Is http dangerous?

Communicating the Dangers of Non-Secure HTTP. HTTPS, the secure variant of the HTTP protocol, has long been a staple of the modern Web. It creates secure connections by providing authentication and encryption between a browser and the associated web server.
