Implement negative lookup cache
Before creating any file negative lookups(1 in Fuse, 4 in SMB etc.) are sent to verify if the file already exists. By serving these lookups from the cache when possible, increases the create performance by multiple folds in SMB access and some percentage in Fuse/NFS access.
