I've updated to 2.4, it do improve quite a lot, but I'm still suffering noticeable (little, but still noticeable) lag while panning, and it takes around 1 second to load the layer when refresh. Is this normal?
You've mentioned about pathological dataset. I'm using MapServer as the WFS server, returns 3 data fields (ID, Name, coord) in GML. Isn't it general? If you were referring to the server side process, I just wondering, does server side process affect the execution flow of the client side? What should I focus on to tune this WFS thing in OpenLayers? ----- Original Message ----- From: "Christopher Schmidt" <[EMAIL PROTECTED]> To: "Jackey Cheung" <[EMAIL PROTECTED]> Cc: <[email protected]> Sent: Tuesday, June 05, 2007 12:29 Subject: Re: [OpenLayers-Users] WFS Layers blocks excution? > On Tue, Jun 05, 2007 at 09:10:00AM +0800, Jackey Cheung wrote: >> I don't know how OL sends out queries.
