[botan-devel] Faster ECC coming in 2.5

Just wanted to drop a quick note that due to a range of optimizations (both low
level optimizations and algorithmic improvements) ECC is several times faster in
the upcoming 2.5 release. For example P-384 ECDSA signatures on my desktop went
from 317/second in 2.4.0 to 2323/second in master, a 7x speedup. ECDH and ECDSA
verification are almost much faster though less impressive ("just" 2-4x speedups).

Probably ECC performance is not the bottleneck in your application, but if it is
you may to to check out latest master and see if the recent work helps.
