This is awesome! Thank you Shawn!
Here are the results of a test I ran today. 4 providers, each on their own distro:
slapd 1. Centos7 el7 slapd 2. AlmaLinux8 el8 slapd 3. Ubuntu20.04 focal slapd 4. Debian10 buster
All using using 2.6.1-2 packages, from our testing repo.
Pumped several hundred thousand entries into the cluster, via the openldap load balancer. As expected, no problems found.
The machines all behave the same and don't care what operating system the others run.
Which is generally what I'd expect, given LDAP is a protocol. The areas where there could be issues due to distributions would be things like:
a) Issues that exist in the kernel that affect things like threading performance b) Filesystem differences that affect I/O rates c) sysctl tuning differences for the TCP layer
One area that could cause issues if using cn=config replication and OpenLDAP binaries that are linked to the system SSL libraries is the differences between GnuTLS and OpenSSL, as the configurations could be incompatible. But in the more general case, the underlying distribution should be immaterial, especially if using something like the packages from Symas which are consistent in regards to OpenSSL and other support libraries.
