Slow performance on SRX110V-HA

Hi, Just setting up a SRX110 with ADSL2+ over POTS. All appears to be configured ok, and inter-zone/inter-vlan traffic looks to be ok however access through the ADSL interface is really slow.

 

Have double checked all the settings and the interface is syncing well at the exchange without errors.

 

If you load a simple webpage like google.co.uk it all works, however if you load a more complex page for example www.bbc.co.uk it stalls and fails after one quick burst of activity which results in only getting the page header.

 

Any ideas, as I am stumped and I have rule out everything other than the device/config?

First thing comes to my head is a TCP-MSS issue.  You could try lowering the tcp-mss
