comparing the performance of different template engines
full featured template engines precompilation to Go code special benchmarks for comparison
Go text/template (do not use this for HTML)
StaticString - Use one static string for the whole Template to have a base
time
DirectBuffer - Use go to write the HTML by hand to the buffer
transpiling to Go Template
Damsel I won't benchmark transpiling
engines, because transpilation should just happen once at startup. If you
cache the transpilation result, which is recommended, you would have the same
performance numbers as html/template for rendering.
Just for fun. Go Templates work nice out of the box and should be used for
rendering from a security point of view. If you care about performance you
should cache the rendered output.
Sometimes there are templates that cannot be reasonably cached. Then you might
need a really fast template engine with code generation.

All packages assume that template authors are trusted. If you allow custom
templates you have to sanitize your user input e.g.
bluemonday . Generally speaking I
would suggest to sanitize every input not just HTML-input.
