> Test file (36MB) is XML document.
> Signing and verifying signature on this file takes 20 seconds, but .NET XML Sigature library makes it ten times faster..
> Bottleneck is canonicalisation. TXFMC14n::readBytes gets too much processor's time while operation. Any canonicalization type works this way.
> Application allocates ~360MB (x86) and ~700MB(x64) while signing. Half of this memory allocates while parsing XML and half while canonisation...
> Its to much, because we need to work with big documents. Is it possible to optimize this operations?
