3DES-MD5-HMAC, Group2, Lifetime 86400, tcp-mss default of 1380
Both systems speedtest out correctly.
Everything negotiates fine and I get a Main Mode tunnel that never drops or has issues...
I have a 50 MB Syncronous connection on one side and a 10MB Syncronous connection on the other side. Â When I do speed testing with IPERF in server mode on one side, client mode on another, I get disappointing results and I'm not sure if I'm just measuring in the wrong units (Mbit vs mbit, Meg/s vs M/s) or if this is VASTLY underperforming. Â Here's what I do, and here's what I get:
On the client side, I connect IPERF using port 20000 with command:
iperf -c [server.ip.goes.here] -L 20000 -d -f m
On the server side, I run default:
iperf -s
my results are:
On Client:
Client connecting to [server IP], TCP port 5001
TCP window size: 0.06 MByte (default)
--------------------------
[404] local [client.ip] port 60701 connected with [server IP] port 5001
[420] local [client.ip] port 20000 connected with [server IP] port 5906
[ ID] Interval    Transfer   Bandwidth
[404]  0.0-10.1 sec  5.66 MBytes  4.70 Mbits/sec
[420]  0.0- 9.9 sec  28.9 Mbits  2.91 Mbits/sec
On Server:
Client connecting to [Client.IP], TCP port 20000
TCP window size: 64.0 KByte (default)
--------------------------
[ Â 5] local [server IP] port 59065 connected with [Client.IP] port 20000
[  4]  0.0-10.0 sec  5.66 MBytes  4.75 Mbits/sec
[  5]  0.0-10.0 sec  4.00 GBytes  3.43 Gbits/sec
Am I getting what you'd expect when the remote end is a 10MB internet connection? Â Or is this bad throughput? Â I had hoped for more. Â I tried dropping 3DES to single DES and the results were almost identical (ever so slightly better, not a huge difference at all).
Thoughts ?

By the way, I am testing throughput with iperf with one setting as client and one running as server, and the results are consistently between 3 and 5M.
Is this a production network, with other network traffic on the ASAs?
If so, it sounds like network congestion.

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
