Bon, je fais des tests et du coup je poste les résultats au fur et à mesure.

Procédure de test

  • Récupérer les tags v1.7c et v15.5b-clementine dans 2 dossiers séparés
  • Récupérer un dump de la BDD datant de la v1.7c et l'importer dans 2 bases MySQL séparées
  • Passer les migrations pour la v15.5b
  • Paramétrer les serveurs en mode DEBUG = False pour éviter les interférences
  • Lancer les 2 serveurs en parallèle et jouer avec ?prof

Ceci garantit que les différences ne viennent pas des données et pas du mode debug.

Tous les tests sont fait sous mon compte (qui est admin, c'est pour pouvoir lancer le profile en mode non debug).

Test sur une page inoffensive

Liste des membres

  • v1.7c : 197 function calls, 0.001 seconds
  • v15.5b : 199 function calls, 0.001 seconds

On vérifie que ce n'est pas un problème généralisé

Sur une page dont le temps de réponse augmente peu

L'accueil des forums

  • v1.7c : 224747 function calls (220822 primitive calls) in 0.403 seconds
  • v15.5b : 237240 function calls (233172 primitive calls) in 0.465 seconds

Les chiffres sont du même ordre de grandeur, le résultat est donc logique.

Résultats bruts - v1.7c

Les deux tableaux de résulta se ressemblent beaucoup, c'est donc logique d'avoir des temps de réponse proches.

Le problème viendrait en réalité des templates : le fichier /virtualenvs/zdsenv-old/local/lib/python2.7/site-packages/django/template/base.py passe de la 3ème à la 1ère place dans les fichiers les plus consommateurs, et l'occupation de /home/spacefox/Dev/virtualenvs/zdsenv/local/lib/python2.7/site-packages/django/template augmente sensiblement.

Cela dit, on dirait quand même que le temps passé dans /home/spacefox/Dev/virtualenvs/zdsenv-old/local/lib/python2.7/site-packages/django/db augmente. Alors on va essayer en mode debug activé pour essayer d'y voir plus clair.

Avec le mode debug

On fait beaucoup plus de requêtes SQL en v15.5 qu'en v1.7 ! 271 requêtes au lieu de 238. Il s'agit visiblement de beaucoup de requêtes du genre :

1
SELECT ••• FROM `auth_user` WHERE `auth_user`.`id` = 258 LIMIT 21

qui sont apparues entre les 2 versions.

Même remarque et même requêtes qu'en mode connecté (153 requêtes contre 129)

Index des forum, déconnecté

Nombre de requêtes presque identiques (79 contre 78)

C'est là qu'on remarque qu'afficher toutes les fioritures des forums est très lourd, puisqu'on passe à 32 requêtes en v1.7 et 33 en v15.5 !

D'après ce que je lis dans ton analyse et ce que j'en lis dans la seule PR qui touche aux forums et à ses catégories, je me dis que les problèmes de performances que tu soulignais étaient peut-être justifiées.

Qu'en penses-tu ?

J'en suis pas sûr, pour moi il faudrait creuser plus en détail que je ne peux le faire ce soir.

PS : par contre ce qui est à peu près sûr, c'est que ces 3 plans d'actions permettraient de gagner pas mal en performances :

  1. Fusionner les 2 tables d'utilisateurs
  2. Trouver un moyen pour qu'afficher une page de forum pour un connecté soit moins lourd
  3. [nécessite django 1.8] passer à Jinja2 pour le moteur de templates
