Performance#

gomarklint is built for speed, with optimizations for both file parsing and external link validation.

Structural checks#

Headings, code blocks, blank lines, etc.:

  • Scanning 185 files and 104,000+ lines takes under 60ms

External link checking (--enable-link-check)#

  • Optimized concurrent validation with intelligent batching
  • ~2,000 external links validated in under 10 seconds
  • Significantly faster than traditional sequential HTTP checks

For rapid local feedback:

  • Run without --enable-link-check → completes in milliseconds
  • Perfect for catching structural issues while editing

For comprehensive validation:

  • Enable --enable-link-check for nightly CI runs, pre-release validation, or verifying newly added content

TL;DR: Fast enough for local dev (no link check), robust enough for CI (with link check).
