I am having a problem with very slow loading of the vxWorks symbol table on an
MVME162 CPU.

I have a bunch of IOCs with MVEM167 CPUs.  These take only 5 seconds to load the
vxWorks symbol table, which is 153837 bytes in size.

My MVME162 CPU takes exactly 50 seconds to load the symbol table, which is
153914 bytes in size, i.e. almost identical size. It takes 10 times longer
than on an MVME167.

The boot parameters for each CPU are the same.

I am booting from a Digital Unix system, so I was willing to blame some quirk
of that system.

However, I just went to another CAT beamline here at the APS.  They have the
identical problem, and they are booting from a Solaris 2.6 system.  Tim Mooney
tells me that he saw the problem for the first time a couple of weeks ago when
he began using Solaris 2.6 for the first time.

Has anyone else seen this problem?  Ideas on what could be wrong?

Thanks,
Mark Rivers
