New document/folder: synchronization of field URL name is too slow

When testing CMS from home (reasonable internet connection) the latency of characters showing up in the url name field is too big.

At first I thought the functionality did not work, but after a few seconds the url name did appear.

For example if I remove 3 characters, i've to wait for 3 - 4 seconds for the url field to sync. Very annoying.

This holds both for new folder as new document dialog, however the latency in Rename document dialog is much smaller (acceptable).
