Default Lock contention

Hi,

During heavy load times I get the following contention (on ASE
12.5.0.3):

sp_object_stats "00:10:00"

Object Name: db..test (dbid=4, objid=572526042,
lockscheme=Datarows)

Row Locks SH_ROW UP_ROW EX_ROW
---------- ---------- ---------- ----------
Grants: 3490 12278 3024
Waits: 144 156 42
Deadlocks: 0 0 0
Wait-time: 293635 ms 2343482 ms 93041 ms

The vendor of the application says that this waiting time is ok, but
in my opinion the application code is the reason for the bad
performance. I have done different configuration changes on the
server, but nothing really helped (around 25% improvement, but it's
still slow).

Any idea what else might be the problem?

Many thanks!

Ulrike
