We have not tested the speed of various messengers for so long, and at first VK Messenger turned out to be in the test, which overtook even Telegram. However, the participants apparently decided not to stop there and restore the work of their service.
The VK messenger has implemented the Server-Sent Events data transfer rate based on the QUIC Internet Protocol (HTTP/3) and new data processing algorithms.
The technology allows you to increase bandwidth, maximize the use of the network channel of the device and reduce the amount of data that is transmitted when sending and receiving messages. With this messenger speeded up message delivery by 20% in all regions of Russia.
Quick user access to communication is our key goal, so we expect to constantly improve our products. VKontakte, one of the first protocols in the world, introduced a new generation of QUIC, which significantly accelerated deliveries. Now this technology operates in VK Messenger.
It makes messaging faster and allows you to stay connected even when the Internet is unstable: on the subway, outside the city or while traveling. We still have many updates in the works that speed up communication, for example, a new logic for loading and caching data.
We will continue to implement modern technologies in all our services for the convenience of users.

The innovation is already working for iOS and Android users.
