From fa331ffc56fb8ead0811a89e4a582bbd5f29d714 Mon Sep 17 00:00:00 2001 From: Christian Borntraeger Date: Wed, 5 Mar 2008 12:37:12 +0100 Subject: [S390] sclp_vt220: speed up console output for interactive work Currently an output buffer can wait up to HZ/2 until the buffer is flushed. The wait time is noticeable in interactive tools like mc. Change the value to HZ/20, which seems enough for interactive work.
