Simple reason, insufficient caffiene; I copy and pasted the command line I used to test the commnad and then partially editted it to use the OP's file name. For clarity the correct test is: dd if=/dev/zero of=zero.txt bs=1024 count=1000000; sync; echo 3 > /proc/sys/vm/drop_caches ; sleep 15 ; time rm zero.txt; On an xfs filessystem this gives: 1048576+0 records in 1048576+0 records out 1073741824 bytes (1.1 GB) copied, 11.3907 s, 94.3 MB/s real 0m0.023s user 0m0.000s sys 0m0.000s 11 seconds create, 23 ms delete.
