EXTREME IMAGE PERFORMANCE FINDING THE BEST WAY
FOR IMAGE DELIVERY

Invitation to a video presentation
At recent Meetups on Web Performance, I had the
enjoyable opportunity to talk about one of the
biggest challenges in web application delivery
delivering ever-larger images faster. Finding
the best possible optimization has a dramatic
impact on the user experience, especially for
small mobile devices with high-resolution screens
and wireless connections.

You probably are aware that images increasingly
make up the lions share of web application
payload, and according to HTTParchive.org the
average page has grown in size by two-thirds in
just two years.
Average images on average pageImages 672

• These recent talks at Web Performance Meetups
  have centered on the effectiveness and tradeoffs
  of the different approaches to image delivery,
  where Instart Logic has gone beyond known
  techniques and created new ones.
• In the video, I coverand compare
• the basics of individual image optimization
  like removing metadata, using browser-specific
  formats, and resizing at the server
• for each requesting device
• progressive Image streaming
• split progressive image streaming
• streaming images in stages of resolution
  without increasing payload
• choosing the best optimization approach in
  each case

Without getting completely into the details of
our secret sauce, I will just explain that on the
server side, Instart Logic treats every web
application, web page, and image as a unique
player in the overall user experience. There is
no one-size-fits-all concept operating we spend
some server cycles to determine the optimal way
to treat every single image going to every end
user. And it works really well. Rather than
spelling it out and expecting you to read through
it here, I invite you to dive into the video and
watch and listen.
I think this video will change, in some way, how
you think about content and applications that you
see on mobile devices, and about the potential
for highly visual content. If you have questions
or feedback about this topic, Id be really
pleased to hear from you at mreshadi_at_instartlogic.
