Packet Loss over OpenVPN Connection

[cjk422]

I'm running pfSense 2.0.1 and OpenVPN 2.3.4 for a remote access VPN. The client is running on Windows 8.1. I can connect to the VPN just fine, but while connected I drop a lot of packets:

PS C:\Users\> ping -n 20 172.16.0.55

Other users don't experience this. I don't see any issues on the firewall itself. I'm really not sure what to check. My local network is behind a Cisco ASA 5505, so I thought maybe that was causing issues, but I can't see anything on that either.
What else can I do to try and troubleshoot this issue? Thanks.

Here's the OpenVPN config file:

dev tun
persist-tun
persist-key
proto udp
cipher AES-128-CBC
tls-client
client
resolv-retry infinite
remote <redacted> 1194
tls-remote vpnuser
auth-user-pass
ca fw01-udp-1194-ca.crt
tls-auth fw01-udp-1194-tls.key 1</redacted>

So I think this is related to the ASA I'm using. I'm connected at another location and I'm not experiencing any packet loss.
