To enable this, configure +Samba using the new option --accel-aes=intelaesni. + +This is a temporary solution that is being included to allow users +to enjoy the benefits of Intel accelerated AES on the x86_64 platform, +but the longer-term solution will be to move Samba to a fully supported +external crypto library. + +The third_party/aesni-intel code will be removed from Samba as soon as +external crypto library performance reaches parity. + +The default is to build without setting --accel-aes, which uses the +existing Samba software AES implementation. smb.conf changes ================ |
