Re: GSOC 2012 - Document speeding up

Hi Dominic,

Thanks for the quick reply. I feel very silly for having said a VM.
I meant a performance analysis tool. Thanks, will work on that, and
come up with some proposals.
A new sample regarding these could also be added to the abiword-testsuite.

Thank you,
Chetan
