Subject: Performance of portable CA server ?

I am finding poor response times for the portable CA server.  Doing a 'get'
for a PV on an IOC gives a typical response time of about 3 msec, rising to
about 10 msec max.  Doing a 'get' for a PV on a workstation running the
'excas' example PV server gives a typical response time of about 100 msec,
rising to 600 msec max.  I get the same behavior under Solaris and under
Linux, neither workstation is heavily loaded.

Can anyone explain the difference, and is there anything I can do to improve
the performance?

Epics versions R3.13.1, R3.13.2
Workstation(s) Sparc 20 w/ Solaris & 450 MHz PII w/ Red Hat Linux 6.2
