Posh: A Data-Aware Shell

Running I/O-intensive shell pipelines over the network requires transferring huge amounts of data but relatively little computation. We present Posh, a shell framework that accelerates unmodified shell workflows over networked storage by offloading computation to proxy servers closer to the data. Posh provides speedups ranging from 1.6× to 15× compared to bash over NFS for a wide range of applications.
