Performance Comparison: Docker Benchmarks and Container Overhead Analysis Across Operating Systems
By
t-3
Crackling crust, pillowy middle. The kind of bagel that earns a second cup of coffee.
Summary
This article appears to be a technical blog post comparing performance of different operating systems and container technologies, specifically focusing on Docker benchmarks and comparisons between container overhead versus FreeBSD Jails and illumos Zones. The author discusses kernel TLS (kTLS) support across different systems and explains benchmarking methodology to ensure fair comparisons across platforms with varying feature support.
Key quotes
· 4 pulledSome operating systems (FreeBSD and Linux) support kernel TLS (kTLS) and the related SSL_sendfile path in nginx, which can improve HTTPS performance for static files.
Since this feature is not available on all the systems included in the comparison (for example NetBSD, OpenBSD and illumos), the benchmarks were run with a common baseline configuration that does not rely on kTLS.
The goal is to compare the systems under similar conditions rather than...
Update: This post has been updated to include Docker benchmarks and a comparison of container overhead versus FreeBSD Jails and illumos Zones.
