Before, one connection was made per action. +This is even done for operations on chunks. So, now storing a chunked file +in webdav makes only 2 http connections total. Before, it would take around +10 connections *per chunk*. So a big win for performance, although there is +still room for improvement: It would be possible to reduce that down to +just 1 connection, and indeed keep a persistent connection reused when +acting on multiple files. + +Finished up by making uploading a large (non-chunked) file to webdav not +buffer the whole file in memory. + +I still need to make downloading a file from webdav not buffer it, and +test, and then I'll be done with webdav and can move on to making +similar changes to S3. -- cgit v1.2.3
