[gnutls-help] gnutls + courier-imap => very slow

[Lenz Weber]

Thanks for the input,
I found it:

It's a bug that apparently was fixed somewhere between
libgnutls26_2.12.14 (which the ubuntu deb is based on) and
libgnutls26_2.12.23 (the latest release in the 2.12 branch).

The newer version takes 1.5 seconds, acually using ~80% cpu, which looks
promising.

Is the 2.12 branch still safe to use? Compiling 3.* has dependencies
that Ubuntu LTS cannot fullfill.

Regards,
Lenz
