Hello,

I've encountered an issue with high memory usage in the latest version. Mercure seems to hang and doesn't respond to publish commands. The average response time now takes up to 3 minutes when the memory is full, and it doesn’t seem to free up memory - it just keeps filling up without using SWAP.

Setting up lru_cache 7e8 1e9 gives an error, I thought it was supported before?

Error: adapting config using caddyfile: parsing caddyfile tokens for 'route': parsing caddyfile tokens for 'mercure': strconv.ParseInt: parsing "7e8": invalid syntax, at /etc/caddy/Caddyfile:30

I don't know maybe it's because of the removal of lru cache #970. Also not sure why some of the bench test was removed?

Maybe we should debug it and try to fix the problem with high memory usage and make Mercure great again :)

Thanks!
