Sampler Is Bottleneck

Metric Description

Sampler stalls EUs due to the full input fifo queue, and starves the output fifo, so EUs need to wait to submit requests to sampler.

Possible Issues

Significant amount of sampler accesses might cause stalls. Consider decreasing the use of the sampler or access it with a better locality.
