| [cdt-dev] Firefox Performance Update |
|
Hey gang, I reran the Firefox performance numbers again from HEAD with
Markus’s new logging data (thanks, Markus!). This is Firefox 2.0 on
Ubuntu Linux on my Athlon 64 2800 box with 512 MB RAM. This time I compared the Fast indexer with the Full indexer.
Here’s what I got: Fast: 2606 source + 4429 headers 527 seconds (8.8 minutes) 532,473 declarations 1,596,258 references 621,308 problems (22.6%) 2,750,039 total symbols Full: 2606 source + 4463 headers 2695 seconds (44.9 minutes) 574,538 declarations 1,967,108 references 251,652 problems (9.0%) 2,793,298 total symbols I found these numbers very interesting and it somewhat
validates the strategy. We are finding almost the same number of symbols during
the parse phase. The big difference is that we are failing to resolve many more
of them, although we are only missing 13% over the ones we already miss in the
Full index (which at 9% given a full parse is a bit disappointing). But the
difference in speed is huge. Doug Schaefer, QNX Software Systems |
