We were making multiple redundant stat calls, especially when looking up resources by ID.
For example, in the gateway, we'd call
getPath
which would stat the ID, and then after performing a few checks on the returned path, call stat again; similarly in EOS FS.This PR brings down the number of such calls from 4 to 1 (for EOS fs) and for the other file systems, by at least a factor of half.
This is a start towards such performance improvements, I'll keep on working on these.
