Barand Posted October 2, 2019 Share Posted October 2, 2019 Recently I have had problems with my broadband speed dropping conderably and there seems to be a strong correlation (causation?) between the speed and if I am connected to this site. When I connect to PHPFreaks the linespeed drops to single figures. Close the browser tab and test the speed again and it's back to normal Seems like something in your page is hogging all my broadband.

requinix Posted October 2, 2019 Share Posted October 2, 2019 Can you use your browser and/or OS tools to find out what is consuming the bandwidth? Hopefully even where it's going?

Barand Posted October 2, 2019 Author Share Posted October 2, 2019 The only activity appears to be an ajax request to check for updates every 60 seconds which takes around 140ms and transfers about 0.5K so it's a puzzle. Yet the effect is consistent - the speed plummets when Freaks is open. Would "Connection: keep-alive" in the request header have this effect, or is it alive only until the reponse is received?

Keep-Alive keeps the connection open for more requests; if there aren't any within some interval one of the sides will close it, and the client will open another next time one's needed. It's to help keep down TCP connection overheads when the browser wants to load a lot of things (CSS, images, etc) at once. It shouldn't have any impact on bandwidth.

requinix Posted October 2, 2019 Share Posted October 2, 2019 It shouldn't. An open connection isn't using any bandwidth - other than small periodic keepalive TCP packets, if any. There's no way it would account for ~30Mbps, and I can't think of a way that one or two open connections would interfere that much with your other connections. Like I said, use your browser and OS tools to get more detailed and specific information.

Barand Posted October 2, 2019 Author Share Posted October 2, 2019 (edited) The plot thickens.... The above timings were using Firefox browser. I just did the same exercise using MS Edge browser ... so it looks like it's the way Firefox handles your page EDIT: Results using Chrome same as with MS Edge, so looks like Firefox is the culprit.

Zane Posted October 2, 2019 Share Posted October 2, 2019 You have any Firefox plugins installed maybe? That could be a culprit. Quote Link to comment https://forums.phpfreaks.com/topic/309317-broadband-speed/#findComment-1570233 Share on other sites More sharing options...
