From 9980b82769e3b0d18720b4381b8426d51337878b Mon Sep 17 00:00:00 2001 From: mav Date: Sun, 6 Sep 2009 19:33:13 +0000 Subject: MFp4: Remove msleep() timeout from g_io_schedule_up/down(). It works fine without it, saving few percents of CPU on high request rates without need to rearm callout twice per request. --- sys/geom/geom_io.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'sys/geom') diff --git a/sys/geom/geom_io.c b/sys/geom/geom_io.c index 61ca41c..c95840a 100644 --- a/sys/geom/geom_io.c +++ b/sys/geom/geom_io.c @@ -567,7 +567,7 @@ g_io_schedule_down(struct thread *tp __unused) if (bp == NULL) { CTR0(KTR_GEOM, "g_down going to sleep"); msleep(&g_wait_down, &g_bio_run_down.bio_queue_lock, - PRIBIO | PDROP, "-", hz/10); + PRIBIO | PDROP, "-", 0); continue; } CTR0(KTR_GEOM, "g_down has work to do"); @@ -672,7 +672,7 @@ g_io_schedule_up(struct thread *tp __unused) } CTR0(KTR_GEOM, "g_up going to sleep"); msleep(&g_wait_up, &g_bio_run_up.bio_queue_lock, - PRIBIO | PDROP, "-", hz/10); + PRIBIO | PDROP, "-", 0); } } -- cgit v1.1
