Still don't see what this does and why it's a good thing...[/quote]studio32 wrote:fs.inotify.max_user_watches = 524288
With inotify, you can tell the kernel 'let me know if this file changes'. Without inotify, you'd have 'poll': hit the filessytem periodically to check if the file has changed yourself. That would lead to disk i/o, which is something you want to reduce to a minimum. AFAIK this setting increases the number of files you can put an 'inotify watch' on.
I seem to remember I copied this recommendation for a fairly trustworthy source, but I can't find it anymore - if I google, all I get is many people running this script .
