Taylor Series expansion performance comparison:

* O/S: Ubuntu, Windows, MacOS

* No library functions employed.

* Golang, Java, Rust, Zig

Configuration:

* X = 0.5

* N = Number of terms = 4,000,000,000

* Compute: exp(X) = 1 + X + (X^2 / 2!) + (X^3 / 3!) + ... + (X^N / N!)

* = 1.648721271 on my calculator app

  

Rough execution elapsed times on Github Actions Ubuntu (does not include compile time):

* Golang and Rust 5.5s

* Java 12.4s

* Zig 16.4s

Measuring execution elapsed times with off-line systems is more reliable than Github Actions (varying system-wide loads).

All times below are expressed in elapsed seconds.

==================

Xubuntu 24.04.up-to-date (Acer A515-44-R2SA, AMD Ryzen 7 4700U @ 4.1 GHz, 16GB DDR4 SDRAM)

* Golang 4.84

* Rust 4.86

* C++ 4.85

* Java 10.64

* Zig 12.27

==================

Windows 11 x64 (IntelUltra 7 155H @3.80 GHz, 32GB RAM)

* Rust 3.77

* Golang 4.32

* Zig 9.94

* Java 22.18 (best result of several runs)
