[Zope] request for advice: using ZCatalog

[Bak@kedai]

hello all
i'm about to jump into uncharted waters (well, for me at least)
i have a news site, and would like to use ZCatalog to present, index, etc 
news.  all's well and good.  
i have a functioning ZClass, that is catalog aware, and searchable.

what i'd like to know is 
-the stability of ZCatalog as of 2.2.5.  
-what's in store in 2.3
-upgradability from 2.2.5 to 2.3
-heartstopping bugs that i may have not encountered yet
-performance speed/response.

with my limited tests[1], i got ok response time, compared to what i have now 
where i iterate through objectItems/Values.  but when i cache with 
CachePool[2], response is better.  correct me if i'm wrong.

i'd like to not go thru what i'm going thru now.

but will this hold water?  especially since i expect more requests.

thanks

Strange how laughter looks like crying with no sound, and raindrops taste 
like tears .. without the pain
