[OpenLayers-Users] Performance?

[Marcos Cobeña]

Hi Jeff,

Just one question, are you calling MS through WMS queries or just
using MS layer recently coded?

If you are using WMS, it seems better to contact MS guys, they'll
surely be able to explain why it takes more time than expected.

Hope this helps.
