 Could multiple files be uploaded in parallel?
 
 Apparently files are also upload to a temporary location and renamed after successful upload. This adds additional latency and thus parallel uploads could provide a speed up?

+Indeed, regular webdav special remote uses prepareDav
+which sets up a single DAV context that is used for all stores,
+but export does not and so creates a new context each time.
+
+S3 gets around this using an MVar that contains the S3 handle.
+Webdav should be able to do the same.
+
+(The upload to a temp location is necessary, otherwise resuming an
+interrupted upload would not be able to check which files had been fully
+uploaded yet in some situations. Or something like that. I forget the exact
+circumstances, but it's documented in a comment where storeExport is defined
+in Types.Remote.)

+Making git-annex export support -J should be doable and could speed up
