Hi,

Threads communicate (I use pthread to manage them) and I want to measure communication time. I found a solution with clock_gettime and CLOCK_THREAD_CPUTIME_ID... (32 Replies)

Hi
I have a system running solaris 10, and I intend to use a NetApp as its storage system. The application requires a throughput between the server and the storage 7000 disk IOPS (random IO sustained throughput with response time of 20 mili second and 16k block size).

malloc_stats
MALLOC_STATS(3) Linux Programmer's Manual MALLOC_STATS(3)NAME
malloc_stats - print memory allocation statistics
SYNOPSIS
#include <malloc.h>
void malloc_stats(void);
DESCRIPTION
The malloc_stats() function prints (on standard error) statistics about memory allocated by malloc(3) and related functions. For each
arena (allocation area), this function prints the total amount of memory allocated and the total number of bytes consumed by in-use alloca-
tions. (These two values correspond to the arena and uordblks fields retrieved by mallinfo(3).) In addition, the function prints the sum
of these two statistics for all arenas, and the maximum number of blocks and bytes that were ever simultaneously allocated using mmap(2).
CONFORMING TO
This function is a GNU extension.
NOTES
More detailed information about memory allocations in the main arena can be obtained using mallinfo(3).
