It's somewhat relevant, given someone's consideration of
migration.
Faster than ours! We have a single at the moment (the VM is
movable so we don't really need it for high availability), but we
are having problems with certain operations (like ls -la /home).
Our case appears as if it might be related to our VM
infrastructure or some tuning parameter that is very wrong. I've
done the usual things (indexing on uidNumber and gidNumber, etc.)
but haven't had a ton of luck so far.
I have to ask the obvious question, which you probably did
already:
Did you do an 'ls -lna' and compare that to 'ls -la'?
Yup, the former is instantaneous, the latter tens of seconds (hence
blaming LDAP).
I'd say that's pretty conclusive. Are you using sssd or nslcd or
something else? What happens when you use ldapsearch directly to query
LDAP? Do you see slowness in that case, too?
