We already discussed the most important performance tweak for TLS because it is not about TLS. You should ensure that your HTTP connections are reusable, because if this is not the case, then you will incur the added penalty of the TLS negotiation along with the TCP overhead. Caching is also very important, and we will talk more about this later.
TLS and HTTP both support compression, but these have security implications. Therefore, consider them carefully. They can leak information, and a determined adversary can use an analysis of them to recover encrypted data. TLS compression is deprecated, and it will be removed in TLS 1.3. Therefore, do not use it. We will discuss HTTP compression later on in this chapter.
