Usage Note 59327: SAS® authentication is markedly slower on AIX as compared to other UNIX platforms
 |  |  |  |  |
SAS authentication under AIX runs much more slowly than it does on other UNIX platforms.
The slow performance occurs because a system file is being opened and closed much more frequently than necessary.
A change was made in the sasauth module to remove the extra file operations, which enables faster authentication through SAS under AIX.
