 # Étudier les performances de Bouncer
 
+## In situ
+
+Il est possible d'activer via la configuration de Bouncer de endpoints capable de générer des fichiers de profil au format [`pprof`](https://github.com/google/pprof). Par défaut, le point d'entrée est `.bouncer/profiling` (l'activation et la personnalisation de ce point d'entrée sont modifiables via la [configuration](../../../misc/packaging/common/config.yml)).
+
+**Exemple:** Visualiser l'utilisation mémoire de Bouncer
+
+```bash
+go tool pprof -web http://<bouncer_proxy>/.bouncer/profiling/heap
+```
+
+L'ensemble des profils disponibles sont visibles à l'adresse `http://<bouncer_proxy>/.bouncer/profiling`.
+
+## En développement
+
 Le package `./internal` est dédié à l'étude des performances de Bouncer. Il contient une suite de benchmarks simulant de proxies avec différentes configurations de layers afin d'évaluer les points d'engorgement sur le traitement des requêtes.
 
 Voir le répertoire `./internal/bench/testdata/proxies` pour voir les différentes configurations de cas.

+# Cache revalidation. Siege supports cache revalidation for both ETag
+# and Last-modified headers. If a copy is still fresh, the server 
+# responds with 304. While this feature is required for HTTP/1.1, it 
+# may not be welcomed for load testing. We allow you to breach the

+# HTTP/1.1 200   0.00 secs:    2326 bytes ==> /apache_pb.gif

+# Siege also supports Cache-control headers. Consider this server 
+# response: Cache-Control: max-age=3
+# That tells siege to cache the file for three seconds. While it
+# doesn't actually store the file, it will logically grab it from
+# its cache. In verbose output, it designates a cached resource 
+# with (c):

+# NOTE: with color enabled, cached URLs appear in green
+# 
+# ex: cache = true
+#

+
+#
+# Cookie support: by default siege accepts cookies. This directive is
+# available to disable that support. Set cookies to 'false' to refuse 
+# cookies. Set it to 'true' to accept them. The default value is true.

+# but it will NOT abort after ten 404s. This is designed to prevent a 
+# run-away mess on an unattended siege.
