As soon as the first file was replicated between the two nodes I wanted to understand the time it took for the file to be available on the second node. Ill call this replication latency. As discussed in my other blog posts, it is important to understand what the limitations are in the system without the Gluster. FS layer. File system and network speed need to be understood so that we are not blaming high replication latency on Gluster. FS when its slow because of other factors. The next thing to note is that replication latency is affected by the type of file you are transferring between nodes.
