Keywords: streaming tape interactive slow Message-ID: <317@focsys.UUCP> Date: 9 Dec 88 22:40:23 GMT Reply-To: larry@focsys.UUCP (Larry Williamson) Organization: Focus Automation Systems Inc. Waterloo, Ontario. Lines: 25 Streaming tape I/O with 386/ix seems to be rather slow. The drive is not streaming very well. It spends most of it's time stopping and starting. I'm using an Everex Excel 60 with a long controller card. The command I've used is find . -print | cpio -ovc >/dev/rmt0 Microport 286 SV/AT has a nice little utility called strm that buffers a large amount of data for the tape drive so that the drive is able to spend more time streaming and less time stop-starting. Is there any such utility for 386/ix? Is there some other secret way to get better efficiency out of the driver? In a foolish act of desperation, I tried the strm program, but although it ran and did not degrade the tape operation, it did not help either.
