Subjectquestion about splice performance
Hi,

I did a really basic benchmark and was suprise about the results.

$ echo 3 > /proc/sys/vm/drop_caches
$ time splice-cp vmlinux /tmp/vmlinux

real 0m10.158s
user 0m0.002s
sys 0m0.401s

$ echo 3 > /proc/sys/vm/drop_caches
$ time cp vmlinux /tmp/vmlinux

real 0m10.590s
user 0m0.017s
sys 0m0.459s


I was expecting splice-cp case to be faster.

Could someone enlight me ?

Thanks

Francis
