ASA 5510 Throttling HTTP Upload SPEED

xfix · ‎05-19-2011

Hi Everyone,

I have an ASA 5510 with Security Plus license. It has 3 Internet connections (2 x ADSL2+ based and 1 x 10/10M Ethernet). ASA is configued in dual ISP mode (2 ADSL connections) providing internet access in case of default route goes down.

3rd connection has recently been installed, i have statically entered a to route (speedtest.net) to forward any traffic for these IP addresses to go through 3rd connection (10m/10m ethernet). When i do a speedtest on speedtest.net it shows me 9.5m download and 1.4m upload.

If i plug the 3rd connection (10m/10m ethernet) directly into my computer and then do speedtest, it results in 9.8m download and 9.5m upload which is close to what is suppose to be, so i dont think there is anything wrong with the actual link, its the ASA which is throttling the upload traffic and keeping them below 1.5m. I have tried different duplex and speed settings but they did not make any difference, at the moment its configured at FULL 100M which is recommended settings by the provider. I have looked at logs nothing gets dropped when i run the tests, no errors on the internet, no crc etc.. There is no IPS module installed.

I also just noticed that if you run FTP test to ISP's FTP server i get around 9m/9m which is acceptable, so problem seems to be only with http uploads.
