Comment	> Please add a paragraph to the documentation (performance guide at > http://www.horde.org/apps/horde/docs/PERFORMANCE), that DNS query > timeouts can terribly slow Horde. There is already a note about > turning off dns lookups for Apache logging, but Horde makes calls to > gethostbyaddr and gethostbyname in it's code, and dns timeouts can > slow the application a lot (like: you must wait up to 10 seconds > after every click). I had only one of three dns servers misconfigured > and Horde was almost unusable, and finding the reason took too much > time. > Maybe it can be fixed somehow in the code, but I leave it up to You. > Appropriate guidelines in docs are enough for me.
