RE: [cdt-dev] Firefox performance report

BTW, the size of the index is 100MB, which is not much more that it was pre-template. I’d expect that to grow a little as we add in the final bits of C++ template info.

Subject: [cdt-dev] Firefox performance report


Hey gang,


My super co-op student Bryan has contributed some work to capture C++ templates in the index. I have rerun my Firefox performance tests and am still getting some great numbers, including a 50,000+ drop in the number of problems reported. Here’s a typical run:


PDOMFastIndexerTask firefox (2594 sources, 5502 headers)

PDOMFastIndexerTask Timings: 403708 total, 157674 parser, 116280 resolution, 102480 index update.

PDOMFastIndexerTask Result: 520670 declarations, 1931668 references, 0 errors, 198547(7.49%) problems.


That’s still under the 7 minute mark which I was timing before the changes. I’m pretty pleased, anyway.


There’s still some more work in the pipe which should help even more.


This is the Firefox 2.0 source indexed on a Ubuntu Linux box with a AMD Athlon 64 (in 32 bit mode) 2800+ with 512 MB RAM.
