-A note about CPU utilization...
-
-For HP-UX 11.0 <= system < 11.23 the configure script will select the
-"pstat" CPU utilization mechanism.  This mechanism is the familiar
-HP-UX idle counter mechanism (for all incense and porpoises) and
-requires calibration.  See src/netcpu_pstat.c for all the details.
-
-For HP-UX 11.23 >= system, the configure script will select the
-"pstatnew" CPU utilization mechanism.  11.23 adds cycle counts for
-user, kernel and interrupt modes to the idle cycle counter.  As such,
-it _should_ be possible to simply take the sum of the four and the
-fractions and know how much time was spent in each mode.
-HOWEVER... there is a bug in the accounting for interrupt cycles,
-where interrupt cycles go missing.  SOOO, since there is an accurate
-way to know what the total number of cycles should have been over the
-interval, and we know (ass-u-me) that the idle cycle counter is good
-(since the pstat mechanism has tested that one OK), we will take the
-ratio of idle to total cycles to compute CPU util.  
-
-We will still calculate fractions for user, kernel and interrupt, and
-report them in debug (-d) output, but with a warning for interrupt
-time.  See src/netcpu_pstatnew.c for all the details.
-
-Up through HP-UX 11.23 (aka 11iV2) if you enable burst mode, and
-happen to send sub-MSS requests and/or responses you _cannot_ assume
-that the packet per second rate on the wire will match the transaction
-per second rate reported by netperf, even if you set TCP_NODELAY with
-the test-specific -D option.  The HP-UX 11.X TCP stack likely will be
-generating some immediate 'standalone' ACKnowledgements which may not
-be generated by other stacks.  This has been reported to the HP-UX TCP
-folks, and an announcement will be made when that issue is resolved.
