[Fedora-directory-users] Slowly the network under control of FDS works

[Сафонов Алексей]

Colleagues!

At me the network on the basis of FDS 1.1 is developed. At the moment the quantity of
computers - clients FDS does not exceed 40. Client computers on the basis of Fedora 10.
Nevertheless, on computers of clients after a while all starts to work very slowly. Slowly
start programs and etc. It occurs only to users FDS. If to come on the computer under the
local user - all is normal.
Tuning of productivity FDS (http://directory.fedoraproject.org/wiki/Performance_Tuning)
has been made.

How it is possible to solve a problem?

Where is the problem ? on clients (run nscd ?) or on the server(s) ?
Can you caracterize better the problem than "starts to work very
slowly" ? What is slow ? Login ? Password validation ?

You'll need to tell more information about your setup, and modules
using LDAP on your clients.
If the problem looks to be on the server, then how it is setup, on
what kind of hardware (or VM hypervisor).

Regards,

J.

Try to use nscd (man nscd for more details) on the clients.

Other than that, index the attributes used during the searches. The utility
that will show you the unindexed searches is logconv.pl ("locate logconv.pl"
to find it):
logconv.pl -V <ldap access log file>

Compared to the the default FDS indexes we add the presence and equality
indexes on uidnumber, gidnumber and memberuid for this type of service. We
have no slowdowns or loss of performance over time with ~10000 accounts and
200 workstations, so for your infrastructure it should be no problem
either...
