Intel opencl Dynamic profiler report

My question aligns with this topic only, so that's why I am asking here. For my OpenCl design i have channel between 2 kernels. So for read and write channel I see in the report generated that my write cycle starts is 40 and read cycle is 4 that leads to stalling at read end and it is affecting the performance as it stalls because of channel is 50%. But I am reading same number of time as writing is , so it should be balanced as such. Do you have any suggestions on how to improve on the end?
