Values are computed 15 rounds + before they are needed. On a Core i7-860, GCC 4.5.2, went from 143 + to 157 MiB/s in SHA-256, and 211 to 256 MiB/s in SHA-512. + +* Pipe will delete empty output queues as soon as they are no longer + needed, even if earlier messages still have data unread. However an + (empty) entry in a deque of pointers will remain until all prior + messages are completely emptied. + +* Avoid reading the SPARC ``%tick`` register on OpenBSD as unlike the + Linux and NetBSD kernels, it will not trap and emulate it for us, + causing a illegal instruction crash. + +* Improve detection and autoconfiguration for ARM processors. Thanks + go out to the the `Tahoe-LAFS Software Foundation + <http://tahoe-lafs.org>`_, who donated a Sheevaplug that I'll be + using to figure out how to make the cryptographic primitives + Tahoe-LAFS relies on faster, particularly targeting the ARMv5TE. |
