Benchmarks

Every package of Deepkit has benchmarks. The comparisons with other libraries use the same data and run in the same process, on a dedicated machine.

Compared with other libraries

Operations per second, higher is better. Deepkit reads the TypeScript types at runtime, so there is no schema to write: the validators check a plain interface User. typia also uses TypeScript types, but generates its code at build time.

Validation of valid data

Checks a user object with nested profile and an array of roles. The result is true or false.

Databases

Complete ORM operations against a real database on the same machine: a table with 10,000 rows, read as entities or objects of each library. Time per operation, the longer the bar the faster. The raw drivers (striped) are the lower bound of what an ORM on top of them can reach.

Releases and master

Time per operation in the last releases and in master, the same benchmarks on the same machine, each with its change to the column before. Compared with 1.0.19, master is faster in 83, slower in 4 and unchanged within the measurement error in 316 of 403 benchmarks.

Over time

Time per operation, lower is better, of whole features from the oldest measured release to master. White circles are releases. The factor compares master with the last release (1.0.19), grey if within the measurement error. Hover a point for its numbers.
