• Status: RESOLVED
• Resolution: FIXED
• Component: Tools / Tests

Loading https://results.webkit.org/?flavor=wk1&recent=false&suite=layout-tests&test=fonts%2Ffont-weight-invalid-crash.html eventually downloads 65.9 MB, of which 65.8 MB is transferred over the wire.

There's little need for so much to be sent, and it's almost entirely uncompressed JSON. For example:

```
gsnedders@gsnedders-margot ~ % curl 'https://results.webkit.org/api/results/layout-tests/fonts/font-weight-invalid-crash.html?flavor=wk1&recent=false' \
-X 'GET' \
-H 'Accept: */*' \
-H 'Sec-Fetch-Site: same-origin' \
-H 'Referer: https://results.webkit.org/?flavor=wk1&recent=false&suite=layout-tests&test=fonts%2Ffont-weight-invalid-crash.html' \
-H 'Sec-Fetch-Dest: empty' \
-H 'Accept-Language: en-GB,en;q=0.9' \
-H 'Sec-Fetch-Mode: cors' \
-H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/18.2 Safari/605.1.15' \
-H 'Accept-Encoding: gzip, deflate, br' \
-H 'Connection: keep-alive' \
-H 'Priority: u=3, i' \
--verbose \
-o results-db.json

```

This shows that there's big savings to be had in how much we're sending over the wire.
