(AIX): UNIX "find" Very Slow On 11.2 ACFS (Doc ID 2018485.1)

Last updated on JUNE 09, 2015

Applies to:

Oracle Database - Enterprise Edition - Version 11.2.0.1 to 11.2.0.4 [Release 11.2]
IBM AIX on POWER Systems (64-bit)

Symptoms

On AIX, the unix command "find" is very slow on 11.2 ACFS comparing with JFS2 or GPFS files systems.

Example of 'find' command used: find . type f | grep -v archi | wc -l

 On similar directory/files structure systems (>400,000 files), the "find" command takes :
- 30 sec with JFS2 or GPFS files system
- Almost 1 hour with 11.2 ACFS


There is no information in the ASM alert log file that points to a root cause.
