I miss some "old" features?! :-( - NBG - 03-23-2018 04:22 AM

Hi,

where are the red/orange/yellow boxes on the top right of the result page showing a-f grades of compression etc.?

Also i miss the "SSL" features... some days ago it showed on SSL sites the source of the certificate... symantec etc.

Where are those features? :-(

Thanks!

The grades should still be there in the vast majority of cases for most browsers. There are a few browsers that don't support it (IE 11 I believe).

The SSL info was never exposed in the UI that I'm aware of but if you use Chrome then the certificate information is in the JSON API results if you need it.

Hi Patrick,

does the visibility of the grades really depend on the selected browser?

Had no problems with Firefox and all those Frankfurt locations in the past...

But since some days no grades on the top right corner:

Also i saw the request of the SSL certificate which slowes down most sites by 250 - 500 ms.

Yes, the grades depend on the selected browser. The gzip and image compression checks both require access to the response bodies and can't be calculated otherwise. I may be able to work out some UI that reports the other grades that only depend on the request metadata (timings and headers) if it would be helpful.

I forgot Firefox doesn't support bodies so it is also not supported there yet. It used to work because the older agents didn't require browser support and intercepted the raw network data but it was Windows-only and fragile (and will no longer work with Chrome). The Firefox dev team is working on exposing better remote debugging support which should make it possible when it becomes available.

The missing ssl checks is a different problem. The Firefox agent uses the supported request details from an extension but also parses the internal logs which have much richer details. It looks like the logs processing broke (likely a change in the messages with a Firefox update). Looking into it now.

Yep, the format of the mozilla log files changed slightly. I just updated the code to handle the new format and the fix is rolling out. The ssl times should be back within the next hour as the update rolls out.

The SSL timings and OCSP checks are back in the waterfall with the logs fix: http://www.webpagetest.org/result/180323_A1_869f303b7353125fd685f7f88ca4aa5b/1/details/#waterfall_view_step1

Great job Patrick! :-)

I think it's very important to keep this SSL feature included since many people think SSL makes their website "faster":

The reality:

Getting the SSL certificate needs 200 ms extra and there are many other (external) connects (to Google Fonts for example) which need to contact a OCSP-server first. This sums up in many ms...

True, but also keep in mind that SPDY only works over HTTPS, so many of those delays are overcome by increased network utilization (ie, more than just a few concurrent connections per server).

Bottom line: test, test, test!
