+# "Legacy" versus "Incoming blobs" pipeline comparison
+# ====================================================
+#
+# This benchmarking aims to compare the legacy and new mail incoming pipeline,
+# to asses performance improvements brought by the introduction of blobs.
+#
+# We use the following sizes in these tests:
+#
+# - headers: 4 KB
+# - metadata: 0.1 KB
+# - flags: 0.5 KB
+# - content: variable
+#
+# "Legacy" incoming mail pipeline:
+#
+# - email arrives at MX.
+# - MX encrypts to public key and puts into couch.
+# - pubkey encrypted doc is synced to soledad client as "incoming".
+# - bitmask mail processes "incoming" and generates 3 metadocs + 1 payload
+# doc per message.
+# - soledad client syncs 4 documents back to server.
+#
+# "Incoming blobs" mail pipeline:
+#
+# - email arrives at MX.
+# - MX encyrpts to public key and puts into soledad server.
+# - soledad server writes a blob to filesystem.
+# - soledad client gets the incoming blob from server and generates 3
+# metadocs + 1 blob.
+# - soledad client syncs 3 meta documents and 1 blob back to server.
+#
+# Some notes about the tests in this file:
+#
+# - This is a simulation of the legacy and new incoming mail pipelines.
+# There is no actual mail processing operation done (i.e. no pubkey crypto,
+# no mail parsing), only usual soledad document manipulation and sync (with
+# local 1network and crypto).
+#
+# - Each test simulates a whole incoming mail pipeline, including get new
+# incoming messages from server, create new documents that represent the
+# parsed message, and synchronize those back to the server.
+#
+# - These tests are disabled by default because it doesn't make much sense to
+# have them run automatically for all commits in the repository. Instead,
+# we will run them manually for specific releases and store results and
+# analisys in a subfolder.
