Zope2 Sprint »

InvasionOftheBlob

Chris checked in changes that allow app code (e.g. foo.index_html) to return a medusa producer instead of a string. In some cases this is a lot faster. To get it, check out zope 2.7 normally, then in the lib/python/ZServer , ZPublisher?, and OFS , do: cvs up -r chrism-publishfile-branch

Using a file_producer could be a big win for binary data that's already on the filesystem, e.g. LocalFS?, ExtFile?, CMF's FSFile?...

Paul checked in a FileCacheManager? that uses Chris' stuff by caching to the fs, and returning a file_producer from ZCache?_get. see http://cvs.zope.org/Products/FileCacheManager/

Preliminary results: a 4 MB file is 2-3x faster when cached by the FileCacheManager?. (using ab -c 10 -n 20). We have not yet benchmarked very small or very large files.

If you can read this text, it means you are not experiencing the Plone design at its best. Plone makes heavy use of CSS, which means it is accessible to any internet browser, but the design needs a standards-compliant browser to look like we intended it. Just so you know ;)
