Subject [jira] [Commented] (COUCHDB-1953) Speed up parsing of multipart/related requests
Date Thu, 05 Dec 2013 10:15:36 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-1953?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13839993#comment-13839993

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.

> 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.
