Slow(er) VPN after replacing PIX with ASA

Just replaced a pix with a asa5520 this last weekend.  Now remote desktop connections from outside in are now much slower to draw the screen, if you are in a email and you scroll down, it takes longer to draw the screen than before. Its something I noticed, then my boss then several VPN users.

Whats strange is that I personally dont use the the PIX or now the ASA for VPN. I use openvpn and it has the same "slower" feel to it when remoted into a desktop on our network from outside.

Generic bandwidth tests are actually faster across the board with the ASA, what are some things to check?

I would check your access lists.

Can you not dedicate a section off your bandwith for this

What model was your PIX?  If it had the VAC+ installed in it, the ASA is indeed slower and it'll stay that way.  It should not, however, be far slower, the kind of thing that will tick people off.

Check your ASA software version.  If you're on a version prior to 8.2, upgrade to 8.2.  Prior versions, particularly 7.x code, are known to have problems with vpn.  

Also verify that your WAN interface on your ASA isn't auto-negotiating to 10Mbps.  Assuming you don't have more than 10Mbps on your internet connection, this won't hurt you on speed tests.  It would, however, cause slowness with things like vpn.  check that interface, and be sure it and the switch to which it's adjacent agree on 100Mbps full.  -TX

@ mredfelix - I'n not sure if I can or cannot, this is all pretty new to me.

@ Texas_Billy - The outgoing pix was 515 and not sure what VAC+ is. I will check the interface's tonight and report back. Thanks!

OK.  Given that, if you're experiencing noticably slower vpn performance, the first place to look is the interface.  Sounds like it may have auto-negotiated to 10Mbps.  --TX
