Finally I got the mount's output from the customer: FS type: vxfs Mount options: ioerror=mwdisable,largefiles,delaylog An additional mount option on production server: nodatainlog So they do not use the 'noatime' option. They run a simple test while dbmon was not running: Count=10 TmpFile=test.$$.tmp time while [ $Count -gt 0 ] do Count=`expr $Count - 1` touch $TmpFile rm $TmpFile done real 0m16.063s user 0m5.180s sys 0m10.860s The result on the similar test server where the disks are idle: real 0m0.115s user 0m0.010s sys 0m0.080s Unfortunately the customer's location is 2900 miles away from me and they don't want to continue the investigation further because "it's just a test server". Thanks to everyone who shared the ideas.
