Hi,
late follow-up regarding the WFS performance issue. What is the current
opinion / status regarding the performance fix? Is MapServer development
going to adress the (yet another) bbox issue?
There are several users around here who would like to know whether and
when they could count on an overhauled WFS access logic to be available?
Could somebody enlighten us?
Missed the discussion? I can resend the pressing points to anybody
interested.
Best, Arnulf.
