Summary: Optimize Ignite main page load performance
Key: IGNITE-7292
URL: https://issues.apache.org/jira/browse/IGNITE-7292
Project: Ignite
Issue Type: Task
Reporter: Denis Magda
Assignee: Prachi Garg
Priority: Blocker
Fix For: 2.4
Attachments: Screen Shot 2017-12-22 at 9.49.02 AM.png
Ignite main page load performance is poor - takes from 3 to 5 seconds to load
in completely. That might affect the SEO optimizations we've done so far. These
are immediate actions to alleviate the situation:
# Reduce banner and all the images size to 72 ppi resolution and save in the
JPG format. Use photoshop "Image Size" dialog. The banner and thumbnails of
screencasts were already changed, just need to regenerate the CSS and merge the
patch.
# The next fierce contributors to the poor performance are screencasts youtube
video. It takes 700ms for each screencast to make a roundtrip to YouTube. See
the screenshot attached where 3 base.js calls are triggered by the video links.
This has to be done asynchronously.
# Preload GitHub, Twitter butter and feed asynchronously too.
The overall goal of this optimization is to speed up the loading to 2.5 seconds
(no more).
