greatroar	5d4568d393	Write sparse files in restorer ... This writes files by using (*os.File).Truncate, which resolves to the truncate system call on Unix. Compared to the naive loop, for _, b := range p { if b != 0 { return false } } the optimized allZero is about 10× faster: name old time/op new time/op delta AllZero-8 1.09ms ± 1% 0.09ms ± 1% -92.10% (p=0.000 n=10+10) name old speed new speed delta AllZero-8 3.84GB/s ± 1% 48.59GB/s ± 1% +1166.51% (p=0.000 n=10+10)	2022-09-24 21:18:48 +02:00

Igor Fedorenko	bda8d7722e	restorer: Optimize empty file restore ... don't create fileInfo structs for empty files. this saves memory. this also avoids extra serial scan of all fileInfo, which should make restore faster and more consistent.
