“These patches add local caching for network filesystems such as NFS,” began David Howells describing an updated set of thirty-seven patches to introduce FS-Cache. When asked how the patches affect performance, he noted that this was dependent on the use case, highlighting issues when dealing with lots of metadata, “getting metadata from the local disk fs is slower than pulling it across an unshared gigabit ethernet from a server that already has it in memory.”
