	Oh - wow, 3.2.1 is pretty old :-) One rather good way to improve
performance, should be to move to using a much more recent build, say
LibreOffice 3.5.4rc1.

	I assume this is from C++ (?) anything else would of course cause tons
of bridging overhead in the streams.

	There is ongoing work to accelerate import; what format of what is in
your byte array ? is it ODF ? 2-4 seconds sounds a lot of time - do you
have a LibreOffice instance around - ie. have you started up the suite
before that, and that's just the load time ?

	HTH,
