eDirectory Scalability for Password Changes


Does any one have any data, or could point me to some documentation in
regards to eDirectory Password Change Scalability? Specifically; along
the lines of "A Novell eDirectory Server can handle _X_ amount of
password changes per minute/hour"

TIA,

Geoff

I don't know of anything that precise, and if it existed it would
probably be out of date the minute it was created. It's going to depend
*primarily* by how fast the disk subsystem and file system are.
Secondarily, it's going to depend on whether you're going to have these
changes all coming from a single thread, or if multiple threads will be
used. Third, it'll depend on your application design; does it have the
full DN of the object to be changed, or is it going to first have to
search for it? Forth, it'll depend on your tree design, but this will be
way down the list.

Best bet, right now, for maximum performance would be a single thread
writing changes, using a Linux OS with (probably) ext2 file system on
solid state disks.

Windows NTFS is not especially fast when it comes to writes, so it tends
to hinder eDirectory performance somewhat.

And to some extend depends on if you're changing NDS password or
Universal Password, and if U/P, how complex your password policy is. And
with U/P changes, there is the overhead of SSL; and for NDS there is the
overhead to generate the hash.

Which also means that the horsepower of the CPU on the server will be a
factor.

True - it'd be difficult to predict what happened if the server were also
running some CPU-intensive application.
