Nginx gzip compression with large responses may exhaust buffers causing CPU spike

When nginx gzip compression is enabled with large client_max_body_size (20M), compressing large responses may exhaust buffers and cache, potentially causing CPU spikes in upstream Gunicorn workers.

Test by disabling gzip compression in nginx config temporarily to see if CPU spikes resolve. If confirmed, tune gzip buffer settings or reduce gzip_min_length, or selectively disable gzip for large responses. Review actual response sizes being served on affected pages.
