Hi,
I am a member of the development team that posted
earlier with subject 'Scalability disappointment'. First of all: we did it
wrong, and we solved most of the problems. We have acceptable performance
now, but it can be better:
Background info
============
Big portions of the site could be cached using
URL-string together with some session-info as a caching-key. We did that in
cocoon1 and that was very fast. However, pages that cannot be cached that way in
cocoon1 are very slow (tens of seconds during havy load). Cocoon2 does
a better job in most parts, except for the above situation. I searched in
the mailing-list but found that I should use a proxy, but I need to gather some
site statistics, that must be inserted in our database. We now use a
logic-sheet, but in cocoon2 it can (should?) be done in an Action.
Timinginfo: with no heavy load (only me clicking)
the minimum load time of a page is 2 seconds. All cached parts are valid. Most
of the time is consumed by executing all the generateKey / -Validity
methods.
Sitemap
============
its 70 lines, so I placed it at the bottom of this
message...
some parts are URL-dependent, some
language-dependent, some country-dependent, some user-dependent....
this seems to be the best structure.
Question 1
===========
Am I correct that there is no CocoonCache like in
cocoon1? I think I'm correct, so:
Question 2
===========
Will there be such a CocoonCache again, or
what is the best place to program it myself in cocoon2? I think I would like to
change the generateValidity() of class ContentAggregator. I actually want to
make a subclass of this and set it up in some external config file, but I cannot
find a way.
I hope someone can help us.
