listfiles
List files recursively, requires cgo.
There are three methods here, it seems one of them is much better on Windows and one is much better on Linux (no tests on OSX). Neither of the better methods if the std filepath.Walk (StdLib).
Benchmarks
On Windows (8-core) with ntfs-formatted SSD and tens of thousands files:
- ListFilesUsingC: 132 seconds
- ListStdLib: 24 seconds
- ListInParallel: 1.8 seconds
On Linux (8-core) with ext4-formatted SSD and a million files:
- ListFilesUsingC: 5.1 seconds
- ListStdLib: 5.5 seconds
- ListInParallel: 7.2 seconds
On Linux (8-core) with xfs-formatted 7200rpm disk and hundred thousand files:
- ListFilesUsingC: 1.8 seconds
- ListStdLib: 3.0 seconds
- ListInParallel: 3.9 seconds

Types ¶
type File ¶
type File struct {
Path string
Size int64
Mode os.FileMode
ModTime time.Time
IsDir bool
Hash uint64 `hash:"ignore"`
}
File is the object that contains the info and path of the file
func ListFilesGodirwalk ¶
func ListFilesRecursively ¶
ListFilesRecursively uses filepath.Walk to list all the files
func ListFilesRecursivelyInParallel ¶
ListFilesRecursivelyInParallel uses goroutines to list all the files
