templ benchmark

Used to test code generation strategies for improvements to render time.

Tasks

run

go test -bench .

Results

Currently getting the following results which show that using an internal bytes.Buffer within a template could save 25% of time.

To put this in perspective, the React benchmark is hitting 156,735 operations per second.

There are 1,000,000,000 nanoseconds in a second, so this is 6,380 ns per operation, which is 6 times slower than templ.
