Technical Article
Summary
This article explores how modern programming languages like Go and Rust have revitalized the performance of 90s-era CGI. By leveraging fast startup times and high-core-count CPUs, CGI can now handle massive workloads, such as 200 million requests per day, on modest hardware.
Highlights
- CGI can achieve over 2,400 requests per second using Go and SQLite on a 16-thread CPU.
- Modern languages like Go and Rust mitigate the startup overhead that previously made CGI inefficient compared to PHP or FastCGI.
- The process-per-request model of CGI is highly effective at utilizing modern multi-core CPU architectures.
- While not a standard recommendation for most, the experiment proves that legacy web technologies can be highly performant with contemporary tools.
