I'm using Smack 4.1.9 for my android app.
I have found that OfflineMessageManager.getMessages(List<String> nodes) method is very slow until it returns a List<Message>.
Regardless of the number of messages, it always takes about 5 seconds.
However, OfflineMessageManager.getMessages() method is quite fast.
What is the cause???
Is this a known Smack bug ??
