Document Table of Contents Low Bandwidth Efficiency

Low bandwidth efficiency occurs when excessive amount of bandwidth is necessary to obtain useful data. Excessive bandwidth usage generally occurs when memory accesses are poor (for example, random accesses), leading to unsatisfactory coalescing opportunities.

Review your memory accesses to see if you can rewrite them such that accesses to memory sites address consecutive memory regions.
