[OpenLayers-Users] reprojecting issues

[pere roca ristol]

   thank you, that is.
   I'm allways missing something about bounds and related issues.

   Currently the server crashed, we usually have problems in terms of
performance, I wonder if  reprojecting (about 6 layers?) and navigating can
substantially decrease the performance? someone with experience in these
issues?

   I'm using Geoserver 1.7.1

  thanks,
  Pere
