New Features: Ignore Defects and Performance Knowledge Base!

 Mark Isham on August 19, 2015. Category: announcements

Another batch of new features for the Zoompf Web Performance Optimizer beta to announce today!

Ignore Specific Defects with Defect Check Policies

Whenever you run a Performance Test with Zoompf WPO, you are testing your site for over 400 common causes of slow performance. These causes include defects such as Content Served Without Compression, Lossless PNG Image Optimization, Unminified CSS, and more. We call each of these tests a Defect Check.

In some cases, though, there may be a set of Defect Checks that are outside of your ability to fix. For example, say your marketing department won’t let you lossless optimize any images, so you’d like Zoompf to stop telling you about them. When this happens, you may prefer to ignore these results in your performance test findings. Defect Check Policies will now allow you to do this.

To configure a Defect Check Policy, visit your Settings page and select the Defect Check Policies tab. You’ll see a view similar to this:

DefectCheckPolicies1

Right away you’ll see a number of default system policies already included in your account (with more to come soon!).

Click the title of any of those policies to browse a read-only view of all the Defect Checks included in that policy. Alternatively, you can create your own new policy by copying an existing system policy or starting from scratch with Create New Policy, for example:

 DefectCheckPolicies2

Click around the tree a bit and you’ll notice a nifty preview window to the right giving you a full description of the Defect Check. This is a great new way to browse all the rich performance content Zoompf has provided in its product for years, but more on that later.

DefectCheckPolicies3

Check the boxes on only the defects you want to test, ignoring the known defects you want to ignore, then click Create to create that policy. Once created, you can then modify any of your existing Performance Tests to use that new Defect Check Policy for all future snapshots. To do this, visit the View Results link in the navigation header,  click Edit on the test you wish to modify, and expand the Scanner Options section.

You’ll now see a new dropdown for Defect Check Policy like this:

DefectCheckPolicies4

Select the new policy you just created, and hit update. All future snapshots for this test will now test only those Defect Checks you selected, ignoring those defects you chose to skip. This is a great way to cut down the noise!

One other tip: If you find yourself using the same Defect Check Policy for most if not all of your Performance Tests, consider setting your new policy as the “Default” on the Defect Check Policies settings page. A default policy will be used automatically for all new Performance Tests created (unless you specify otherwise in the test). Note, you will still need to modify existing tests to use any new policies you create.

To get a better understanding of which tests are using which policies, use the new Defect Check Policy filter in the left hand filter bar on the View Results page.

New Performance Knowledge Base!

You may have noticed while you were browsing the Defect Check Policies all the great performance content visible on the right hand preview pane. While this content has been in the Zoompf product for quite some time, it was always a little buried and harder to access: you’d have to first run a performance test to view this content, and even then you’d only see content for those defects that were found.

With the addition of Defect Check Policies, we felt now was a good time to make all this great content much easier for you to access. Therefore, we’re happy to announce our new Performance Knowledge Base!

Accessing the Knowledge Base is a snap, just log into your WPO account and click the Knowledge Base button on the top nav.

DefectCheckPolicies6

From there, you’ll see a read-only view of the Defect Check data we mentioned above, but easily browseable so you can view any topic of interest.

DefectCheckPolicies7

There’s over 400 articles in there, so you’ll have a lot of late night reading to keep you busy :-). We’ll also be continuing to add more content over time, so keep coming back for new updates.

We’re really excited about these new features and hope you’ll find them useful. And of course, if you have any feedback on how we can improve this (or any other feature) please feel free to contact us with your feedback!

Enjoy!
