Hi All,
I did complete Cognos 11.0.5 single server installation. And started to use it through default servlet gateway URI. I oberved its very much slow when I use through IE11 and its comparatively better when Chrome is used. Anyone else observed similar issue ?
I have the same experience as you are.
Also found couple of issues like
1. Cannot see FM model tables using IE 11
2. Cannot test Data Server connections using IE 11
I am using IIS Gateway with two server configuration. Are you having the above issues??
