Hi Seb, thanks again for your fast answers.
Interesting to know that its because of the improved security checks.
I guess I can live with it.
Eventhough the response times seem longer, the platform is table.
I will try to vacuum and reindex the database tonight.
Yet I guess it does not help much, since I did with the migration a dump/restore.
So the database should be in good shape
I will observe how it performes under load starting next week. If necessary I will try to upgrade the hardware.
Also lets see what LS 2.3 can do
I am looking forward to it.
