Extremely slow performance

I am having extremely slow performance on all computers I use with gcsf. Reading and writing files appears synchronous and can take hours to transfer a large number of files, but also just listing the root directory can take thirty seconds or more.

Is this expected behavior?

Start by reproducing the reported behavior in gcsf: time listing the root directory and reading or writing many files. Compare the results across the reported operations and determine whether the delays and synchronous transfers match the intended behavior; done means the performance cause or expected behavior is documented and the issue has a concrete resolution.
