+# This benchmark is the simplest test of the I/O facilities in

+# Adjusting this benchmark is done via the "bs" (byte size) and "count"
+# environment variables.  "count" designates the count of elements of
+# "bs" length in the Rack response body.  The defaults are bs=4096, count=1
+# to return one 4096-byte chunk.
