Tnsping time over WAN - is this slow?

Hi all,

Have the following tnsping results from a WAN.

Network to server is a 128kbps ISDN line.

Average 400 milliseconds, peak of 1200 ms (yes, 1.2 seconds!).

The protocol is tcp/ip, with tcp/ip ping times averaging 65ms, peak 190ms.

To me, the tcp/ip layer is OK, but the tns/sql*net layer is very slow. Other WANs I've examined typically have 150ms to 250ms times for tnsping.

Clients claim they are doing "nothing big". However, I do know they use the Oracle client app, as well as groupwise, a scheduler, and possibly a few other network apps.

Client is a pentium with winnt 4.0 workstation. Only other protocol is NetBEUI over tcp/ip - this appears to be configured OK.

Your opinions out there?

Ciao
Fuzzy
