Why, yes, Kerika did get faster

If you are wondering whether Kerika is faster than it used to be, yes, it is.

We made a change in our software architecture — the way each board would connect to the server and ask for all its cards and all the updates on these cards — that has reduced the total upload of data.

This was actually a significant improvement in upload speed: about 10x.

Since upload speeds are frequently much slower than download speeds, even on broadband connections, this should help load larger boards much faster.  And on mobile connections this should help reduce the amount of data consumed.
