Proposed performance improvement is described in TWiki:Codev/JumpBoxSlowInLargeWebs
After some iterations, I did a first cut on improved speed and usability, SVN 11956:
- Jump to topic form field, on top.
- List up to 16 similar topics, in reverse order
- Show link to "list more similar topics" (if any)
- Show link to moved topic, in red (as before)
- Show link to create new topic (removed form)
Possible further enhancement: Do a SEARCH for similar topics and moved topic only if URL param topic is present. This will speed up the "topic not found" error even more, unless used via jump box.
SVN 11958 is now suppressing the SEARCH for similar topics unless the Jump box is used.
