Well, I've written the backend - but I didn't compare different 
backends (e.g. mysql vs. ldap) for performance.

Only a few. LDAP is most useful in corporate environments for 
centralized management, so it serves only 4 domains with ca. 300 
entries for me. Easy management, stability and failover are more 
important than serving million of records at maximum speed for a 
domain hoster.

But without tests, I wouldn't say the ldapbackend isn't capable to 
match the speed of a relational database. There is also a chance that 
it outperforms a RDMS, because LDAP was designed for top read 
performance at the cost of write performance.

Maybe it would be nice if the do, but that isn't the case in 99,99% of 
all installations. You also don't set up a mailserver and read SMTP 
RFCs before.
