I would add another approach to speed up small file access and metadata in general. The approach would be something based on delegations (also known as leases or oplocks in some contexts). This should dramatically reduce the number of network requests for normal workloads and give faster answers (less latency) to many requests. Also, if this is combined with samba, for example, the perceived speed from the user side would be really good, specially with small files and directory browsing (AFAIK samba supports leases and oplocks to further extend this approach to the client workstation). The limitations of this approach will be scenarios where multiple clients access the same files, or O_DIRECT/O_SYNC access is needed. In any case, I think this is complementary to the other proposed solutions, and combined with them could bring quite a good throughput to gluster.
