slow browsing while fast file download on satellite Internet link
Posted on 2009-06-30
I have 2-way satellite broadband internet link using iDirect satellite modem (Please note that using 2-way satellite internet is subject to latency of min 600 ms to the 1st hop). When I download a file from HTTP, I got fast downloading rate like 400 kbps and same as when uploading a file to HTTP web page.
The problem is on browsing web pages. Once a web page called through a browser, the page download part of its content and then hold up waiting the other parts. Such waiting may exceed the time up setting of the browser and hence the browser give up while the page has half contents. To solve this issue, I have to force reloading/refreshing the page about 3-5 times.
This happen on all web pages even those that are famous like Google, Yahoo, MSN, Experts-Exchange ...etc. I'm tried most popular web browsers like Firefox, IE8, Chrome and Flock all latest versions but with no help!
It seems to me that on multiple TCP sessions towards HTTP resources get some to be broken during downloading them. While on a single download TCP session, the session get fast downloading speed.
What kind of web accelerators do you suggest that internally designed for satellite links having high latency? Perhaps using TCP optimization for satellite links is a necessity?
I'm using Vista 32-OS in case you would like to suggest an optimization tool or web accelerator tool.
Thank you in advance ...
