I'm not an expert on how Hydra's set up these days, but will > assume it's not too different from my own (a fast nginx proxy_cache, > mirror.hydra.gnu.org, in front of a slower build farm, hydra.gnu.org). I think there’s room for improvement in our nginx config at <https://git.savannah.gnu.org/cgit/guix/maintenance.git/tree/hydra/nginx/mirror.conf>. For instance, I just discovered ‘proxy_cache_lock’ while looking at <http://nginx.org/en/docs/http/ngx_http_proxy_module.html>; looks useful in reducing load on hydra.gnu.org. Surely there are other ways to tweak caching. Besides, I’d like to use ‘guix publish’ on hydra.gnu.org. I suspect it’s going to be faster than Starman (the HTTP server behind Hydra), and also it uses an in-process gzip by default, as opposed to bzip2 which is what Hydra uses (better compression ratio, but super CPU-intensive). At any rate, clients should not paper over server-side performance issues IMO. Thanks, Ludo’.
