 Changes in the current code since fc-host-tools-r11:
 
-* In an attempt to be nicer to those users who prefer to run newer Linux kernel
-  versions than the Mother's own preference for older host systems, our default
-  Linux version of libserial (the serial port access library underlying all of
-  our tools) now sets the ASYNC_LOW_LATENCY flag in TIOCSSERIAL.  Prior to this
-  change, poor performance has been observed on newer Linux host systems where
-  the select system call waiting for serial input would wait some extra 10 ms
-  before returning, majorly slowing down many of our operations.  The present
-  change is hoped to alleviate that problem.
+* To facilitate objective comparison of loadtools performance between what the
+  Mother sees on her Slackware reference system vs. what other users see on
+  their different host systems, fc-loadtool now reports measured operation times
+  for all lengthy operations: dump2bin, dump2srec and all flash programming
+  commands.  fc-xram likewise reports the measured operation time for its
+  singular operation of transferring an XRAM image.  The new
+  doc/Loadtools-performance article explains some of the underlying theory and
+  presents the performance numbers which you SHOULD be getting if your host
+  system works as well as the Mother's Slackware reference.
 
 * fc-loadtool: added support for Spansion S29/S71PL032J and S29/S71PL064J flash
   chips found in some modem modules; historical flash chip Am29DL640G is also
