WebSo this optimization could be vital as we try to make Gluster competitive in performance. Use case: lower latency for latency-sensitive workloads such as single-thread or single-client loads, and also improve efficiency of glusterfsd process. Improvement: no data yet WebThe flexible I/O tester tool sends write calls of 1 Byte. For a sequential write, if a write call on a dispersed volume is not aligned to strip size, it first reads the whole stripe and then calculates the erasure code and then writes it back on the bricks. As a result, these Read calls have their own latency thus causing slow write performance.
