Yes, we did a slew of PSU patching as part of our new PSU conflict detection support, and PSUs are slower in general, but HPUX boxes, which are notoriously slow in general, have a particularly rough time. Even on our Linux VMs, a PSU application takes ~30 minutes, and since the process is single-threaded, having multiple CPUs makes only a small performance increase. I can get more exact timings from our QA team if you like.
Thanks,
Matt

Subject: PSU on HPUX - how long does it take you
I have blogged several times regarding PSU patches and I had a comment from Peter Wiseman today stating that his application of the 10.2.0.4 PSU took over 2 hours on a HPUX IA64 server compared with a few seconds on an AIX server. The delay is around using ar to make a copy of each file.
I only have experience of PSUing (!!) on HPUX so I would welcome views from other people as to how long it takes. Most of our servers would have 2-4cpus and a backend SAN with the 11g ones using ASM with 2 disksgroups (one disk in each - external redundancy) although the big servers with multiple disks still take around 40 minutes
