| |
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
