I've managed to create a new set of pages with CRC performance data during my hobby time this summer.

"Best" CRC Polynomials:

http://users.ece.cmu.edu/~koopman/crc/index.html

This contains an extensive list of of good CRC polynomials for different CRC sizes and dataword lengths. I re-ran all the computations in light of some data that has become available since the initial publication a number of years back. The table is slightly different than the table I previously published. The old table is OK, but this one is marginally better than the old one for the data that was previously provided, so there is no pressing need to change systems based on the old version so long as you were running at shorter than 2Kbit dataword sizes. More importantly, this new table consideres unlimited dataword lengths and larger CRC sizes. (At this time the 32-bit computations are still running and they'll be updated as they are available.)

CRC Polynomial Zoo with Hamming Weight Data

Contains error detection performance data for a large variety of CRCs, including numerous "standard" and published CRCs. If you see one missing let me know with a citation and I'll add it.

I hope that this data is useful to others. Some of the large polynomials have incomplete or shortened data files, and will be updating those over time as the computations complete.
