libumem - object-caching memory allocation library
SYNOPSIS
cc [ flag... ] file... -lumem [ library... ]
#include <umem.h>
DESCRIPTION
Functions in this library provide fast, scalable object-caching memory allocation with multithreaded application support. In addition to
the standard malloc(3C) family of functions and the more flexible umem_alloc(3MALLOC) family, libumem provides powerful object-caching ser-
vices as described in umem_cache_create(3MALLOC).
The libumem library also provides extensive debugging support, including detection of memory leaks, buffer overruns, multiple frees, use
of uninitialized data, use of freed data, and many other common programming errors. See umem_debug(3MALLOC).

Hi all,
I have written the following program and run on both T5440 and T5220 on same OS version. I found that T5540 server takes more time than T5220. Please find below the details.

We are migrating Pro*C code from SOLARIS to LINUX-Redhat.
While migrating we face memory de-allocation issue intermittently when accessing large volume of data.
Below is the part of the code(since code is big I am putting the part of the code where the issue comes):
