EFS Performance mode.
General Purpose is ideal for latency-sensitive use cases, like web serving environments, content management systems, home directories, and general file serving.
Recommended for the majority of Amazon EFS file systems.
File systems in the Max I/O mode can scale to higher levels of aggregate throughput and operations per second.
This scaling is done with a tradeoff of slightly higher latencies for file metadata operations. Highly parallelized applications and workloads, such as big data analysis, media processing, and genomics analysis, can benefit from this mode.
