Sequential read performance from LTFS
posted by Ken Spickler on June 8, 2018, 6:35 p.m. (1 day ago)
Does anyone have any slick tricks to improve read performance of a DPX sequence from an LTFS tape? I'm trying to restore a large DPX sequence from an LTO7 and it's painfully slow. Doing a "cp" from the tape is getting me about 6- 4K DPX frames per minute. For giggles I also tried "cvcp" but that was no better. The tape is using the default options for LTFS.

TNX,
Ken
