[...] As you can see, there is always a 30-40 seconds delay between the "Request" line and "Parsed query". That cannot be explained by partial searches. Note that Poor/WhoGo/Pure maps cache the search results and will not bug the server if the string is the same as before. So, to search again, you would have to close/open the map client. Time difference between request and parsed query is induced by libpostal. So, in your case, that's a performance limitation (RAM/CPU/all together). Not much can be done by me here, unfortunately.
