TEMPE, Ariz., May 9, 2011 (GLOBE NEWSWIRE) -- Limelight Networks, Inc.
(Nasdaq:LLNW) ("Limelight") today announced the acquisition of
AcceloWeb, a Tel Aviv-based provider of advanced technology that helps
speed the presentation of web sites and applications.

"The web application acceleration market is large and growing rapidly
as enterprise and consumer applications migrate into the cloud -- one
of the three macro trends core to Limelight's strategy. The talented
AcceloWeb team has built the most innovative solution in the sector and
we are excited to join forces with them to define best-in-class for
this market by rapidly deploying their software worldwide on our high
performance compute, storage and delivery platform," said Jeff
Lunsford, chairman and chief executive officer, Limelight Networks,
Inc.

AcceloWeb's technology, combined with Limelight's web and application
acceleration services, will help customers dramatically improve "Time
to Action" on their websites. Time to Action is the amount of time an
end user will wait in order to perform tasks on a website or within a
web application. By speeding the performance of Limelight's Portal and
Commerce Accelerator services, AcceloWeb's patent-pending technology
will increase conversion rates, decrease abandonment, and improve the
return on a customer's marketing investment.

AcceloWeb's technology addresses the bottleneck of presenting a site or
application within a browser. The technology requires zero
configuration and no pre-optimization, and does not require any changes
to existing web development workflow, reconfiguration of site or
application resources, installation of a hardware appliance or any
server side, browser or desktop plug-ins. Click here to see a short

"We're pleased to join Limelight and continue our work building
Internet scale software that improves end-user experiences on the
Internet. We are excited about the opportunity that Limelight's global
resources and technology platform offers the AcceloWeb team," said Ofer
Gadish, CEO, AcceloWeb.

This transaction was completed with a combination of Limelight Networks
common stock and cash. YL Ventures, headed by Yoav Andrew Leitersdorf,
participated in the transaction as an investor, strategic advisor, and
board member. Terms were not disclosed.
