From 786335b9673f9c3af0b3897799b30b205e99748a Mon Sep 17 00:00:00 2001 From: hdzhoujie Date: Fri, 5 May 2023 20:00:25 +0800 Subject: top: lessen summary cpu distortions with first display When the cpu utilization is displayed for the first time, the reading of the /proc/stat file is very close to each other, resulting in large fluctuations. The version before refactoring, such as v3.3.17, has a delay before reading the /proc/stat file for the second time, and the same delay is added here. signed-off-by: zhoujie signed-off-by: he jingxian Signed-off-by: Jim Warner --- src/top/top.c | 3 +++ src/top/top.h | 2 +- 2 files changed, 4 insertions(+), 1 deletion(-) diff --git a/src/top/top.c b/src/top/top.c index 757b8d3..98444fd 100644 --- a/src/top/top.c +++ b/src/top/top.c @@ -3735,6 +3735,9 @@ static void before (char *me) { Graph_cpus = alloc_c(sizeof(struct graph_parms)); Graph_mems = alloc_c(sizeof(struct graph_parms)); #undef doALL + + // don't distort startup cpu(s) display ... + usleep(LIB_USLEEP); } // end: before diff --git a/src/top/top.h b/src/top/top.h index d633f3e..03de1ca 100644 --- a/src/top/top.h +++ b/src/top/top.h @@ -121,7 +121,7 @@ char *strcasestr(const char *haystack, const char *needle); /* Length of time a message is displayed and the duration of a 'priming' wait during library startup (in microseconds) */ #define MSG_USLEEP 1250000 -#define LIB_USLEEP 150000 +#define LIB_USLEEP 100000 /* Specific process id monitoring support (command line only) */ #define MONPIDMAX 20 -- cgit v1.2.1
