[Freeipa-users] Want faster user-add

[Daryl Fonseca-Holt]

Hi all,

Environment: RHEL6 with IPA 3.0 at current RedHat level. 64-core 256-GB 
RAM Oracle x4470 M2.

During our migration from NIS on Solaris 140,000+ accounts will be 
added. After tuning per the guides dbmon.sh shows no roevicts and we get 
high cache hit ratios.

Per a previous discussion with the list the input is broken down into 
batches of less than 1,000 users and the default IPA group is changed 
before each batch. This helped greatly.

Adding all the users takes many hours. Initially ipa user-add takes an 
average 2.3 seconds per user but degrades by the time there are 140,000 
users to an average 6.7 seconds per user.

In tracing it appears that a significant portion of the time ipa 
user-add takes is not the add itself, it is the query at the end that 
displays the resulting user account. Is there any legit way to prevent 
this query?

The length of time it takes to migrate is not a big concern. The concern 
is the start of the fall school term when we typically add approximately 
1,300 accounts per hour during the registration period with our current 
system.

All suggestions will be appreciated.

Regards, Daryl
