Nick North commented on COUCHDB-1953:
-------------------------------------
Continuing with Alexander's benchmark question: I tried a "worst case"
attachment - a 750KB Windows text files with lots of "\r\n" content. The new
code is about 10 times faster in this case.
> Speed up parsing of multipart/related requests

>
> Parsing of multipart/related requests searches for the MIME boundary string
> using the couch_httpd:find_in_binary/2 function, which can be made more
> efficient.
> When the boundary string is not found in its entirety in the search data, the
> function should then look to see if the data ends with a prefix of the
> string, but it currently looks for any prefix of the string almost anywhere
> in the search data.
> A pull request to fix this will be submitted shortly.
