Subject Axis of Performance improvement of Resource Download ?
Date Thu, 11 Aug 2016 18:53:38 GMT

Today, when we activate the "Download embedded resources" in Http Request
this has a certain CPU impact related to HTML parsing to extract the links.

Do you think it would be interesting to cache the parsed links based on the
MD5 of the file (similar to what has been done in 59885).

The difference here is that HTML will vary much more than CSS content, so
we may end up computing MD5 (which eats some CPU) for nothing and in the
case of a mandatory LRU cache clearing too frequently parsed pages.

What do you think of this optimization ?
Is it useless ?
