Question

Latency spikes during uploading of photos to facebook?

Feb 2, 2013 1:43PM PST

I realize that a few milliseconds of spiking should occur, but my latency spikes to 1500ms. What do I need to do to fix this, because this certainly shouldn't happen this dramatically.

If you are on WiFi, then could be normal.

As WiFi is subject to interference and long periods of delays. Also, facebook can delay seconds as things work themselves out. I know folk that are newer to computers and the internet and every little delay they are posting on forums and calling their internet providers. It's working, just not as well as folk want.

that can't be

No, that can't be, because i've been running off WiFi for over 3 years. Never have had a problem. I think i''m going to need to call my ISP.

Then you get to call it in.

WiFi is open to interference and not a sure connection. And as folk think that it worked fine before they often won't accept any change in performance.

I see this issue a lot and think it will create a lot of income for the support folk.

Bandwidth

Plus Bob, over 3 years there may have been an increase in susbscribers within the area to create MORE bandwidth draw/drain not to mention theossibility of the issue being created by something nefarious happening during the download(s)...and you are right, keeps the support folks employed.

wifi's not the problem
Feb 3, 2013 12:42AM PST

I know wifi interference isn't the problem. i've narrowed this down to my upload stream sucking all the bandwidth during an upload. for instance, i started to upload a video to facebook, meanwhile i had "ping -t" set on my modem. everything was hovering around 10ms, until i started uploading that video then it spikes to 900-1800ms with a very large jitter. has never done that, and i'm pretty sure it shouldn't.

Now think about that ping.

Why should servers service a ping quickly? It's a waste of their time so no real reason to answer it.

But that is not where I want to go here. As you are successfully uploading a video to a big site, you don't have much to get support yet for. It works, just that it pauses at times.

Also, on WiFi it's half duplex, but you know that.

Finally, it appears you have only this issue with this one site. Why do you think there is something wrong with your computer or network?
