At V5.2 there was a new DNS Lookup routine that was added to the TSM server code.  
This might be your problem.  Simply add "DNSLOOKUP NO" to the DSMSERV.OPT file and 
restart your server.  For more inforamation on this you can search 
www.ibm.com/software/support for DNSLOOKUP. The document is locked so I am adding the 
text below but the format may not look that great.

Error description
This problem may be reported in two ways:.1) slow initial connection for ITSM client 
sessions with   command line clients - dsmc.exe dsmadmc.exe - after   upgrade of ITSM 
server to 5.2.0.0 or higher..2) poor performance with Web interfaces after upgrade of  
 ITSM server to 5.2.x.x..At 5.2.0.0 level of ITSM server, additional OS calls 
wereadded to perform DNS lookups with the "gethostbyaddr" call.."gethostbyaddr" is a 
system call which causes a DomainName Serverlookup to occur. A long delay may be 
caused ifthere are no DNS entries for the client system connecting.The client system 
may be behind a firewall (non-routable)or using DHCP without DNS services. This would 
result inthe DNS lookup timing out, which could cause a delay whenconnecting in to 
ITSM server as it waits on the return ofthe gethostbyaddr call..With the Web Admin, 
this call to get DNS information ismade multiple times, so the issue may be reported 
as ageneral performance issue with web interface..To diagnose if 
 this is
 the issue, enable tracing on ITSMserver for "tcpinfo" traceclass and recreate the 
slowinitial connection or poor web admin performance..In the trace look for the 
following lines: tcpcomm.c  859 : tcpQueryAddress: rc 571147392 from inet_addr for 
128.4.11.34 tcpcomm.c  870 : tcpQueryAddress: rc 0 from gethostbyaddr input address 
(null) output addresses 128.4.11.34.If there is a sizeable delay before the 
"gethostbyaddr"call returns in tcpQueryAddress, this APAR applies..Customers can 
verify DNS problems by running "nslookup"command against the connecting IP address of 
the client.This command should be run from an OS command prompt on theITSM server 
system..In above example this would be:  nslookup 128.4.11.34.Initial Impact:

(dsmserv.opt) and recycling ITSM Server:   dnslookup no

Hi listers,

I've installed ITSM V5.2.2.3 an have a catastrophically response times
working with the web administration tool on any workstation.

Before we are running V5.2.2.3 we are using V4.x and the web interface
runs fine.

Does anyone have an idea what that can be?


Thanks in advance
