Re: [Netatalk-devel] [Netatalk-admins] Request for Comment: Deprecate CNID backends

[Daniel M. <da...@mi...>]

Hi Andres,

Thanks for your suggestion. We have an option for CNID dircachesize in afp.conf already. Is this akin to what you are asking for? The documentation says:

====
dircachesize = number (G)

    Maximum possible entries in the directory cache. The cache stores directories and files. It is used to cache the full path to directories and CNIDs which considerably speeds up directory enumeration.

    Default size is 8192, maximum size is 131072. Given value is rounded up to nearest power of 2. Each entry takes about 100 bytes, which is not much, but remember that every afpd child process for every connected user has its cache.
====

See https://netatalk.sourceforge.io/3.1/htmldocs/afp.conf.5.html

Also, "dbd" is what we call the CNID backend in question. We have some documentation in the manual: https://netatalk.sourceforge.io/3.1/htmldocs/configuration.html#CNID-backends

Best,
Daniel
