The overhaul will also prepare the microblogging service for the next generation of web browsers by laying the ground for more interactive features.
“This new framework will help us rapidly develop new Twitter features, take advantage of new browser technology, and ultimately provide the best experience to as many people as possible,” said Twitter engineer Dan Webb in a blog post.
The changes, which are currently being introduced across Twitter.com, will also do away with the “hashbang” symbol in its page addresses.
The “#!” symbol in Twitter URLs was used as to tell web browsers to fetch and render tweets requested by the user, but now much of that work will be handled by Twitter’s own servers.
“The bottom line is that [the old] architecture leads to slower performance because most of the code is being executed on our user’s machines rather than our own,” Mr Webb explained.
