If NVDS read performance is critical to your software architecture, you can optimize your
code for speed. Try the first suggestion below before attempting the second.
1. Periodically refresh all addresses that are used. The optimal use of NVDS in terms of
2. Use as few unique addresses as possible to optimize the impact of refreshing, plus
speed is to rotate the writes evenly among all addresses planned to use, bringing all
reads closer to the minimum read time. Because the minimum read time is much less
than the write time, however, actual speed benefits are not always realized.
