        It'd be good to know what is in that sequence :-) is it zipped ODF
data, flat ODF ? etc.

        Sounds very odd; if this is a linux machine - can you run a sampling
profiler like oprofile to work out what is happening there - almost
certainly something very dumb is going on - we should be able to stream
data from a python bytesequence at great speed: it should be ~all native
code from there on in IMHO - so something very odd going on :-) perhaps
some unusual filter / type detection stuff (?).

        Thanks !
