+Even though it cannot be a replacement for fc-loadtool in most use cases, FLUID
+is very aggressively optimized for speed in ways that would be hard to match in
+our fc-loadtool architecture.  Therefore, on those targets which are supported
+by both FLUID and fc-loadtool, flash programming with FLUID is faster.  Here
+are the performance numbers, flashing an Openmoko GTA02 modem with firmware
+version moko-new-fw-20190128, going through the external headset jack,
+UberWaves CP2102 Professional cable:
+
+fluid-mnf   at 115200 baud: 2m28s
+fc-loadtool at 115200 baud: 4m02s
+fluid-mnf   at 812500 baud: 0m40s
+fc-loadtool at 812500 baud: 1m12s
+
+With both tools the m0 version of the firmware image (fwimage.m0) was being
+flashed; in the case of fc-loadtool the new flash e-program-m0 command was used.
+The version of fc-loadtool used for this test is the one that is about to be
+released with fc-host-tools-r13; previous versions would be even slower.  In
+the case of fluid-mnf the -C option was used to disable delta downloads, making
+the test operation independent of previous flash state.
