Small file workloads are mostly because of number of network round trips
before doing anything useful with them. The features we are working on to
deal with them are slowly coming out nicely. 1) Compound-fops (Anuradha was
working on this before she left for college to pursue her MS, now Krutika
is leading this work. i.e. instead of multiple operations over network, we
send one compound operation that does the work), 2) Improvements in caching
of metadata (Poornima is leading the work here improving the md-cahce
feature), 3) -ve lookup cache which will reduce the number of lookups to
check if a file exists or not(I am doing this work).
