Summary: listinfo: cache

Initial Comment:
We`re running more than 700 lists on our  
mailinglist-server. Mailman needs between 20  
and 40 seconds to generate the public listinfo  
page.   
  
Wouldn`t it be possible to generate a  
listinfo.cache including all these necessary  
informations to speed up the process?  
  
These listinfo.cache could be valid for some  
specific time, before it is removed and  
regenerated. Or this cache-file can be  
deleted if somenbody is changing his list  
configuration.  
 
Thanks...

I have to post again my problem. And it is REALLY a problem. 
 
Generating the listinfo-pages takes much time and Mailman uses 
more then 74 MByte of memory. We need so much memory in our 
server just for beeing able to generate the listinfo page even if five 
or six users try to access the listinfo-page at the same time. 
 
I can`t set up a server with 2 GByte of memory just for a listinfo 
overview page. 
 
And, anyway, it takes TO MUCH time.  
 
I don`t know how to programm python, but I can`t imagin that it 
should be so hard to integrate a caching mechnism. 
 
If this problem will not be solved in the near future, we have to stop 
using mailman, because Mailman isn`t enough designed to perform 
even on big mailingliste-server. :-(((((((( 
 
PLEASE!

I`d like to refresh my wish. With more then 1.000 lists on 
our server we really need a cached listinfo-overview. 
Building a listinfo-pages takes several seconds (as you 
can see on http://listi.jpberlin.de) and this only works 
if not too many different users try to access this page at 
the same time. 
 
I`d prefer the following model: 
 
Mailman generates a listinfo.pck or something like this, 
including all necessary information. If listinfo.pck 
doesn`t exist, Mailman generates a new one. 
 
This listinfo.pck has a lifetime after which it is deleted  
(e.g. 5 minutes). 
 
After creating or deleting a new list the listinfo.pck is 
deleted. 
 
Possible: After changing the configuration of a list 
Mailman deletes listinfo.pck which means, that the general 
lifetime cat be set up to 10/15/20 minutes, because 
everytime something SHOULD have changed, Mailman SHOULD 
have deleted listinfo.pck... :-) 
 
Isn`t that possible? That shouldn`t be too much work...

Having more then 700 lists on our server we now 
have problems generating the listinfo/admin 
overview-page, because the http-timeouts are 
faster then mailman :-) 
 
Is there something planned to solve the problem?
