Google Cloud Messaging just got a big revamp during the big Google I/O conference held in San Francisco on Wednesday, and it's now a whole lot faster.
Last year, it announced Google Cloud Messaging, which lets you push data from servers to apps. Now, about 60% of the top 100 apps in the Google Play store use it today. About 200,000 push messages are sent each second.
"GCM now supports connections between a persistent connection from servers to many devices as quickly as possible," a Google spokesperson told attendees. "It is also launching upstream messaging to send data in the other direction -- from the app to servers."
It also is launching a new API that syncs notifications across devices.
"All of the new features are rolling out progressively, and all you have to do up is sign up starting today," he added.
