On the search page, there is a note that the indexes are updated every 3 hours. The fastest I've been able to re-index has been 6 hours. Does anyone have any hints on how to index faster?
Using a SSD has reduced the index time on my machine from about 9 hours to 3½ hours.
And maybe you can use the script "updateindex.sh" instead of recreate the full index on every run.
updateindex,sh does not really work
Make sure are allocating sufficient memory when reindexing.
IIRC that's no longer exactly true: some indexes are updated every hour or two (like artist) and some once or twice a day (like recording).
