More work on less hardware.

Recompute your deltas, smartly.

We make software faster with patent-pending mathematics.

From C++ and Linux to Python, COBOL, and Java, Delta Routing can extract more performance wherever a hot path has an incremental operator.

But I already optimize my hot path.

Hot-path tuning makes each operation faster. Delta Routing changes the amount of work.

What is the operating envelope?

An incremental operator updates a fixed hot-path operation from the input that changed.

p is the fraction of the input that changed. p=1 means the whole input changed.

Progress has always meant doing more with less.

We measure what changes in your system.

Then we optimize your hot path using Sparse Compute Matrix Math.
