RE: [libreoffice-dev] - questions about calc extension

Hi Kohei,

Using unlockController/lock brought down the time from 12sec to 3sec. Using DataArray brought it 
down to 14ms!
 Thanks for the tips. Great thing about starting with bad code is that I get to feel happy when it 
improves :-)

Hi Michael,

Who would have thought it was a script :-) Maybe 0 bytes callgrind should have given me a hint.
I am running callgrind now. Although, I don't need to based on above numbers, I am sure I'll write 
the next code as badly and will need it soon.
I never said in the email that I was running the wrapper but you figured it out anyway.
Thanks for catching it.

You guys are great.
Neeraj

        It should be ~instant - sub-second anyhow; it's an analog of loading
values from ODS. Kohei's suggestions are great:

        You'd need to run callgrind like this:

export OOO_DISABLE_RECOVERY=1
valgrind --tool=callgrind --simulate-cache=yes --dump-instr=yes ./soffice.bin

        ie. on the soffice.bin not the wrapper script ;-)

        HTH,

                Michael.
