ISD 10.UC5 installing on AIX 5.3

HI, We installed IDS 10 UC5 on AIX5.3. onstat -version: Program Name: onstat Build Version: 10.00.UC5 Build Number: N202 Build Host: ibm6c1b Build OS: AIX 5.2 Build Date: Thu May 18 00:09:08 CDT 2006 GLS Version: glslib-4.00.UC8 oslevel: 5.3.0.0 My question is, to enable AIO in AIX, sounds we have two options: run command smitty, smitty >> Devices >> Asynchronous I/O: Posix Asynchronous I/O Asynchronous I/O (Legacy) Which one should we turn on? Posix Asynchronous I/O or Asynchronous I/O (Legacy) ? Looks , it would be EXTREMELY slow if we turn on " Posix Asynchronous I/O" when we do dbimport! We use raw devices. Any explanation or recommendation are appreciated.
