I have an issue that when users connect to my ASA 5520 via SSL VPN it takes from fifteen seconds to three minutes to open up small Microsoft Word documents, it also takes a long time to save changes. Users also reporting Word crashes when on the VPN, but not when they are on the LAN. I have checked the endpoint speed of my cable modem and all is well there. The DNS and WINS settings are correct on the ASA. I have turned off compression and enabled DTLS. Any suggestions? Thanks
Reduce the mss to 1300. If that doesn't fix it, keep lowering it by 100 each time. If you get down to 1000 and it still doesn't work, then we need to look at something else.
As far as I know the SSL clients and anyconnect clients have the MTU setup under the group policy, you can try to play around with that want too
