Example with wget:
wget --no-parent -rpk --wait=1 --random-wait --adjust-extension --convert-links https://wbsite.com/page
--no-parent prevents going up in the URLs
--wait=1 --random-wait slows down request and add jitter to go easy on the server
--adjust-extension --convert-links fixes links containing parameters to work with simple files

| # Benchmark: checking whether a single serial is revoked in a CRL. | |
| # A) OpenSSL::X509::CRL#revoked.find { ... } (only API available today) | |
| # B) X509_CRL_get0_by_serial() (proposed, via Fiddle) | |
| # | |
| # Each approach runs in its own forked process so the reported peak RSS reflects | |
| # only that approach. Requires MRI on Linux (uses fork + /proc; falls back to | |
| # Process.getrusage on macOS/BSD). |
