Network - Headers tab taking 10 seconds to load?

[Ryan Q]

Ever since Chrome 50 opening the Network - Headers tab is taking almost exactly 10 seconds ( way too long to be a useful tool, used to be unnoticeable load time)  just to view maybe a few KB worth of request / response data while working in local environments (Doesn't seem to happen with live domain requests (e.g. to aws resources). I noticed the tab for Chrome's process spikes up to 30-40% CPU usage, which leads me to believe it's a bug.

There isn't any crazy amounts of cookies or weird headers going on here, as it's consistent regardless of the project I'm working on.

This also happens when opening the Network view if the last request had the header tab selected (since Chrome saves the state of the last tab viewed).

Anyone have thoughts on what is causing this? I'm not exactly sure what to post to be useful here, but let me know if anything comes to mind.

Can you please supply us with live example?

Hi Ryan. Are you seeing this behavior in incognito mode?

My colleagues and I are seeing this as well. 10 seconds. Seeing the behavior in Incognito mode as well.

Again, it is extremely difficult to fix an issue that we cannot reproduce ourselves. The best thing would be to file a bug @ http://crbug.com/ PLEASE PLEASE PLEASE give live examples or explain in detail how to reproduce this.

Example here:

link to google search with long query string

In devTools, Network -> headers tab, you can find that switch between other tab and Headers tab took a lot of time.

(if the parameter is shorter, the switch is very fast, we assume problem is the long query String, and this kind of problem won't happened in Firefox or safari.)

Hope this helps.

I investigated the issue and looks like a layout problem with contiguous text. I submitted a bug and will ensure devtool's needs will be satisfied.
