+# Run Multiprocessing Test
+# ========================
+#
+
+# This script measures the time of several interactions with the Blobs Server
+# and outputs them to a text file.
+#
+# The different test scenarios are:
+#   - 1, 2, 4, and 8 server processes.
+#   - several client actions (baseline, list, put, get, flag, delete)
+#   - 
+#
+# Client actions
+# --------------
+
+# Baseline: is a GET / to a dummy server that returns an empty reply. Nothing
+# can be faster than this.
+
+# List: is a GET /blobs/username, which lists the (empty) set of blobs stored
+# in the server.
