Dear colleagues
I don't know why I never had this to come into mind before, but:
Do we have an option to disable the trackback pingback checks by entry on save?
Serendipity is now saving your entry, creating trackbacks and performing possible XML-RPC calls. This may take a while..
I don't know .... I just made an entry note, gathering a lot of other pages content to my personal private blog as a reminder entry and then had to wait minutes for the xmlrpc calls. Since that is private, I would not need this at all. This is the situation where this question came up to my mind.
