This is a matter of profiling; when you say "quite a long time" - how long are you talking ? :-) Also, is your concern cold or warm startup time ? > - It won't work if there is already a LibreOffice instance running That should be easy enough to fix; it's a matter of not checking the OSL_PIPE that we setup to send arguments to the main process. It is possible that --nolockcheck does that, or perhaps there is a hidden argument for that. > So my boss asked me to fix these 2 issues.

So - --headless doesn't work well for Mac, there is a need for some work there to fix it. There are really two different approaches - one is to re-factor the font code so it is re-usable without setting up the display / head logic, the other is to build & use freetype on mac, and re-use the Linux code for font rendering etc. There are also some nice sillies going on; last I looked there was some considerable proportion of the time rendering a nice gradient background to a bitmap view of the window you can't see when using --headless ;-) I suspect just profiling and turning off a lot of that fluff would accelerate things for you. But -always- profile before optimisting. Callgrind-for-mac + KCachegrind on Linux would be a great pair of free tools if you have nothing better. > I found out that to just do the conversion, there are many dynamic > libraries are loaded (so I guess this is why it takes a long time). That's not obvious to me, and I've done lots of work on profiling. If you want faster cold-start, you can try using the --enable-mergelib build mode - that builds a ton of the code into a single, huge library - it may help you: I'd be interested in some hard profiling results from that. > Trying to understand what's going on in the code is not a simple task > to be honest.

Build light weight conversion binary
Hi, The company that I work for use LibreOffice as the main word processor. We convert a lot of client letters from doc/docx to open document format. We are on Mac OS X Lion (10.7) btw. We use: soffice --headless --convert-to odt …. to do the batch conversion. The problems with this are: - It takes quite a long time to start up. It becomes a problem when we have to convert many documents. - It won't work if there is already a LibreOffice instance running So my boss asked me to fix these 2 issues. I managed to build the source code on Mac OS X Lion and then try to see what's going on (unfortunately specifying --headless fail to build). I found out that to just do the conversion, there are many dynamic libraries are loaded (so I guess this is why it takes a long time). Trying to understand what's going on in the code is not a simple task to be honest. Can some one help or give me info on how to: - build a bare minimum/small binary (without too many dependencies) just for conversion to odt? also how do I link statically? The conversion utility doesn't need all the gui libraries I believe. Minimum dependency will make start up a lot quicker. - what to do to allow conversion working while there is an instance of LibreOffice already running? Should I modify something in the source code? I'm sure a lot of people would love to have this light weight conversion utility. Many thanks before.
