The NICs are 6x1Gbit (teamed on hyperv). Metadata caching improves performance in almost all the workloads, except for use cases with most of the workload accessing a file sumultaneously from multiple clients. Improving GlusterFS performance keeps file operations responsive and prevents small storage stalls from turning into application retries, lock contention, and cascading timeouts. You can configure if it should really do a flush () or do that later in the background. To increase the Small files performance is still the Achiles heel of GlusterFS.
