How much impact of network connection to LDAP on CLM performance?
The network connection among CLM VMs (WAS cluster nodes, DB2, proxy servers) is about 1GiB/s. The CLM is configured with MS AD to manager users. However, the MS AD VM is on another network and the network connection from CLM to the MS AD is about 300Mbps.
I am wondering how much impact of the connection speed to MS AD on CLM performance? Should I need to created a MS AD server within the same network to take advantage of the 1GiB/s connection speed?
Thanks and regards

Hi Ralph,
Thanks for the information. How about the impact on the 1st logon page?
I would try and if people complain, I think it would be relatively easy to change the LDAP settings. You could also set up a test system first.
Hi Frank,
On our environment which access a LDAP server via an firewall the first logon varies between 60-90 sec, subsequent logon took less then 30sec.
Hi Nhi,
Thanks for the information. 30sec is still long to me:-)
Is the firewall setup within your CLM proxy/servers? Or on the network(domain) layer outside your systems?
Thanks
Hi Ralph,
Here are the scenarios:
1. Subnet A: LDAP, CLM1
2. Subnet B: CLM2 (more RAM and CPU cores than CLM1) using LDAP in Subnet A
I found accessingCLM2 is quite slower than accessing CLM1. I am checking if the LDAP is the cause or the firewall between these two subnets is causing this. Some tips are appreciated.
Hi Frank,
if using Federated Registry, you might want to read this recent article :
