I was having similar issues with one of my DSpace instances the other day. In my case it turned out that there was a stale lock file in the index directory, which led to delays when DSpace tried (and failed) to update the search/browse indexes. Have a look in your [dspace]/search directory (or wherever else your search.dir parameter in dspace.cfg points to). In particular, check - when the files in the directory were last modified (as far as I know, these files should be updated basically whenever you add/delete an item or change an item's metadata) - whether there is a file in that directory with the extension .lock or .lck (sorry I can't remember which one it was) I could solve this by manually deleting the lock file and then manually updating the indexes once ([dspace]/bin/index-update). Also, make sure you always update the indexes as the standard dspace user (in our case tomcat, but I think it'd be dspace if you followed the standard installation instructions) so that the file permissions in [dspace]/search are correct. Incorrect permissions for this directory and its files may be another reason for the delays you're seeing, if indeed they are linked to index updates.
