Download Speed on PIX 515E is Pretty Slow

Hello, I have a PIX 515E set up between our office switch and our Comcast Business Router and the download speeds are not as fast as they should be. We are paying for 30 down 30 up but it's more like 10 down 30 up. I plugged in a computer directly into the router and got 30/30 so I know its not a comcast issue. I think it might be the low amount of memory on the PIX because its running at 109 out of a total 128mb. The PIX has a site-to-site VPN tunnel with a remote ASA 5520 firewall. The inside/outside ports are both auto/auto. The running config is only 161 lines.

Here's some information about the PIX 515E...

Version 8.0(4)

ASDM 6.1(3)

Memory 128MB

Here is the running config..

Re:Download Speed on PIX 515E is Pretty Slow

Hello jack,

1. When you connect links directly to the laptops or desktops, they adjust the mtu to the best available for throughput.

Try changing the mtu on the pix to a lower value on decrements of 32 and test.

2. Try no service-policy global_policy global once. Since you mentioned download is slow.

Download Speed on PIX 515E is Pretty Slow

Hi Bro

Personally, I don't think this is a Cisco FW issue. However, I stand corrected. Before we conclude anything, could you fix the Eth0 and Eth1 port speed/duplex to 100FULL. Next, could you place a laptop directly to the Eth0 interface and verify once again the download/upload speed?

Hi Jack,

Please check on the speed and duplex settings whether the downstream and upstream links are fine and healthy.

Check for the processes usage of the cpu of the pix.

Check on the inetrface whetehr u get any crc/input/overrun errors. Please check with the physical connectivity.

enable flowcontrol recieve on on the firewall interfaces and switch/router interfaces connected to the firewall.

Please do rate if the given information helps.

The MTU was the problem, ran a bunch of pings with a do not fragment option until I got to 1272 so 1300 is my MTU. Speeds are closer to what they should be now. We recently switched to Comcast Business and I guess their MTU is 1300. Thanks everyone for the help!
