Speed comparison of the three DI libraries Katana, Koin and Kodein.
Also see this independent comparison.
Please have a look at the source code. The test is divided into the two blocks setup and execution. Setup tests how fast the test subject is in setting up the dependency injection (creating modules, bindings, etc.) and execution tests the actual injection. The test collects the average and median time in nanoseconds of 1,000,000 iterations of each block.
| Library | Version |
|---|---|
| Katana | 1.7.1 |
| Koin | 2.0.1 |
| Kodein | 6.3.3 |
For fairness towards Kodein the erased version of Kodein was used for this comparison. It should be faster since it doesn't use reflection.
The test has been performed on a 2017 MacBook Pro with a 3,1 GHz Intel Core i7 CPU, 16 GB RAM, macOS Mojave 10.14.6 and Java 1.8.0_222.
All times in nanoseconds.
| Library | Setup (average) | Setup (median) | Execution (average) | Execution (median) |
|---|---|---|---|---|
| Katana | 793.377251 | 527.0 | 259.320590 | 181.0 |
| Koin | 969.294944 | 509.0 | 370.726363 | 254.0 |
| Kodein | 1629.850542 | 951.0 | 809.621470 | 566.0 |
