New SSL Timing in Waterfall Chart, Capacity Upgrades, and Other Updates

Whew! A lot of general improvements and maintenance were completed in this release.

---

 

Added New SSL Time Bar

SSL coecting time now appears in the Waterfall Chart for relevant requests.

 

SSL time was actually always part of Coecting time (the Green bar) – it will now be displayed as a dark green/light green bar.
 

 

Upon hover, the SSL time is indented under the Coecting time.

Added regex filtering ability in Dashboard filter

You can now use regular expressions to filter for URLs in the Dashboard filter.

 

Type in ! to switch over to regex mode – you’ll notice the magnifying icon change over to a regex icon, indicating the mode switch. If a regex error is detected, the icon and input border will turn red.

Waterfall Chart Improvements

Some details regarding the Waterfall Chart updates.
 
 

Upgraded HAR Viewer to the latest version

We upgraded HAR Viewer to latest (February 2019), which came with a few new features:

 

 
 

Various UI adjustments

A few changes were made to streamline UX of the Waterfall Chart.

• Changed “Size” column to match Firefox and Chrome (Firefox/Chrome also include response header size in “Size”)
• Hid “GET” method text unless it’s another HTTP method
• Hid HTTP status text and show it in the hover instead
• Show the query string for root requests (e.g. /?foo=bar)
• Enabled middle click on request URL to open in a new tab
• Improved cached request
• Fixed visual issues regarding layout alignment, text-wrapping, etc.

Page Details and Recommendation Changes

Two changes were made with regards to scoring and page details.
 
 

Disabled “Remove query strings from static resources” recommendation

The main reason why Google PageSpeed recommended removing query strings was due to some proxy caching servers (namely Squid up to version 3.0) not caching resources with a “?” in the URL string.

This is no longer the case (since Jan 2015) and we’ve removed the recommendation to reflect this.

We still feel that excessive “?” in query strings are not advisable however, so if you are using them do ensure they’re used sparingly.

Fixed Minification handling bugs related to ES6 template strings and RegExp syntax

Bug fix affects only the Minify JavaScript recommendation. Resulting score will be adjusted.
 
 

Adjusted calculation for “Total Page Size”

This was done because it previously didn’t match the value displayed in the Waterfall Chart.

Previously the calculation included “request size”; This latest update sees “request size” removed.
