Optimizations stories¶
Start¶
A zope and plone 25 bulk will be our testLand
Test procedure:
Make some changes
Run and store the following ab2 test:
/usr/sbin/ab2 -n 100 http://hostt/> a_filename
Errors levels¶
debug off
error level -> error
Setted in the buildout.cfg
[project] log-level = ERROR debug = off session-timeout-minutes = 90
ZODB¶
Try to change the cache size from 5000 to 10000 & see
<zodb_db main>
# Main database
cache-size 10000
# FileStorage database
<filestorage>
path /home/kiorky/projects/zope/minitage-0.4/zope/test-perfs/var/filestorage/Data.fs
</filestorage>
mount-point /
</zodb_db>
result : 3,47, little improvment nothing wonderfull
Http cache¶
Metadata files¶
Adding .metadata for images and static content:
title=$(basename "$filep" "$ext") echo "Generating metadata for $filep" echo "[default]" > "$filep".metadata echo "title=$title" >> "$filep".metadata echo "cache=HTTPCache" >> "$filep".metadata
Http headers control¶
Test on “parts/plone/MimetypesRegistry/skins/mimetypes_icons/quicktime.png” which has no metadata by default Without:

Python optimize mode¶
We must set the PYTHONOPTIMIZE envrionment variable to 1.
RAMCACHE¶
- This is a very good manner to cache python scripts.
- Add a ramcache to the site and associate content types with it.
- We can add also templates and etc and tweak the cache key with the http request variables.
Cachefu¶
- Set up various plne settings for caching policies. Its a great product.
- things important to know is that cachefu can run in a standalone mode or run behind a classical http cache proxy like squid.
- It monkeypatches several products to wrap the methods against its caching ones.
- We can add easily rules throught the plone back office too.
- As an example, locally, Cache fu in zope only mode == x30
