|Subject:||Drastic performance degradation between 1.63 and 1.77|
As described in, we encountered a huge Math-BigInt performance regression when upgrading from RHL9 to CentOS 5. In RHL9, the Math-BigInt version was 1.63; in CentOS 5, it's 1.77. I also tried the current version of Math-BigInt, Math-BigRat and bignum, and they had the same problem, so I assume that everything between 1.77 and 1.87 has this problem. You can reproduce the issue by invoking the function mentioned in that bug report; it takes a packed 8-byte integer, most significant byte first, which specifies the number of 100-nanosend intervals which have passed since January 1, 1601 (ugh!).
