the problem of speedup used opencl in imagemagick

[zhong xiao bao]

Is it used opencl can faster than not used opencl .
frst find convert.exe and the command line i put in is : -convolve 16 d:\pic\1.jpg d:\pic\1.bmp
and another is :d:\pic\1.jpg d:\pic\1.bmp

the status of used opencl
Event Comsuming Time : 520.89ms
the status of not used opencl
Event Consuming Time : 96.6793ms
I think used opencl can acclerate the program ,but I don't know why used opencl is slowly than not used opencl

[magick]

Curious. Its been a about a year since we benchmarked OpenCL but when we did we got a significant speed up for image convolution with OpenCL. We'll revisit the benchmark and report back here but it may take a week or two.
