Compatibiliy view will only affect the html/css display and have no bearing on downloads.  

As for the "request timeouts" once connections make it into the Peak 10 facility - that is because we have ICMP restricted at the firewall level for security purposes.  It's not an indicator of any sort of issue or bottleneck.  Whatever is happening is occurring somewhere en route to the data center at Peak 10 outside of anything we can directly control.  If the bottleneck were in fact at the Peak 10 level, then everyone would be experiencing the same issues with download speeds.
