[Kolab-devel] Kolab_Format

Hi Alexander,

That sound great ;)

Probably depends on the size of the entries but memory consumption is  
an area where Kolab_Storage as well as Kolab_Format still need to  
improve.

Hm, this is something you should probably use Kolab_Storage for rather  
than Kolab_Format. Kolab_Storage includes the IMAP handling.

I guess this relates to the mail structure. Do you see in the log file  
what might be causing this?

Not without a lot of scripting (which you just started). I'm currently  
actively working on the Horde4 libraries and just today started a  
command line interface for Kolab_Format. Depending on when you want  
you to have your task complete you could use this. But I don't expect  
this to be completed before the end of January.

Needless to mention that I can also be contracted to speed some parts  
up or provide a rough toolset for the Horde3 libraries.

Not significantly. I extracted the class construction into a factory  
today but I don't expect the load() and save() functions to change.

I think the desired "healthy size" is 10.000 entries. But I know this  
is already pushing at the Horde boundaries. When I rework part of the  
Kolab_* libraries for Horde4 now the time factor and memory  
consumption will be critical points.

This should only happen once though. All the clients should cache  
their data and only sync new objects from the folders. This should be  
completely independent of the amount of objects you already have in  
the folder. Or are you killing/repopulating the address folder each  
day? That would not be a good idea :)

Cheers,

Gunnar
