james commented on JAMES-1440:
------------------------------
hi,
i used codes as follows to test pop3 and imap‘s capability of
james.it is so slow when use imap to connect server and get unread mail count
when there are more than 30000 mails. it is also slow to connect server with
pop3 when the count of mail attain to 100000.
public static void main(String[]args){
Properties pop=new Properties();
//set pop
//.................
Session session=Session.getDefaultInstance(pop);
String host="",username="", password="";
Store store= session.getStore("imap");
//it is slow when using imap protocol
store.connect(host,username, password);
Folder folder = store.getFolder("INBOX");
folder.open(Folder.READ_ONLY);
int count = folder.getMessageCounts();
//it is slow when using imap protocol
int uncount = folder.getUnreadMessageCounts();
}
> Imap receive mail when there are many mails
