Why is my mSQL authentication terribly slow?
You have probably configured the Host by specifying a FQHN, and thus the libmsql will use a full blown TCP/IP socket to talk to the database, rather than a fast internal device. The libmsql, the mSQL FAQ, and the mod_auth_msql documentation warn you about this. If you have to use different hosts, check out the mod_auth_msql code for some compile time flags which might – or might not – suit you.
