The WebDAV implementation is definitely not the one that provides best performance in BaseX. Nevertheless, I think I’ll have a look at the use case you describe. Some questions in return:
> I re-verified the behavior on a third (fast) machine with SDD and the result > as still bad with an average of 900-1000ms per request. 1. What does "request" mean in that context? Do you request directory entries, do you request documents, or do you run updates? 2. Does the eXist-db WebDAV implementation list multiple databases in the WebDAV root directory (as BaseX does), or do all operations work on a specific database that is chosen at startup time?
