In practice, I haven't measured that yet. The new stack is still missing support for high-speed cards.

I just haven't had time to do such tests, and in general work on the stack during the last three months due to ENOTIME. -- Ilya --CXFGmo39UtQ0Pg54tr3KTbb29tULrFGCQ-- --GsE7U9TOlDrjMKRmxKpEcLNa4RxsBl90J Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Comment: GPGTools - https://gpgtools.org iEYEARECAAYFAldgUl8ACgkQo9vlj1oadwgThgCaAkLeyLCXU+Cv+ZHkZ4G8kfJE MGQAoOpS5pkRmClkUqjYP/NFkseax92J =yLII -----END PGP SIGNATURE----- --GsE7U9TOlDrjMKRmxKpEcLNa4RxsBl90J--
