extreme mem usage under amd64 arch ?

[patrick]

Hello,

Hope someone can shine a light for me on this,

I have several boxes running STABLE 4/5/6

one of them is amd64/stable6 on dual opterons.

I notice that on this amd system the httpd 2.2  and perl 5.8.8 binairies 
alocateds a lot of memory:

76562 www              1  20    0   156M 38528K lockf  0   0:00  0.00% httpd
76561 www              1  20    0   156M 38528K lockf  0   0:00  0.00% httpd
76830 www              1  20    0   155M 37740K lockf  0   0:00  0.00% httpd
76560 www              1  20    0   155M 37736K lockf  0   0:00  0.00% httpd
76563 www              1   4    0   155M 37736K kqread 0   0:00  0.00% httpd
61338 root             1   8    0   155M 37668K nanslp 0   0:02  0.00% httpd
73328 root             1   8    0   142M   102M nanslp 0   0:03  0.00% perl5.8.8
73611 root             1   8    0   142M   101M nanslp 0   0:03  0.00% perl5.8.8
75475 root             1   8    0   142M    99M nanslp 0   0:02  0.00% perl5.8.8
76966 root             1   8    0   142M    99M nanslp 0   0:02  0.00% perl5.8.8
75736 root             1   8    0   142M   101M nanslp 0   0:02  0.00% perl5.8.8

The binairy self has normal size:

~$ ls -lah /usr/local/sbin/httpd
-rwxr-xr-x  1 root  wheel   510K Apr  6 22:46 /usr/local/sbin/httpd

~$ ls -lah /usr/local/bin/perl5.8.8
-rwxr-xr-x  2 root  wheel    12K Mar  4 09:48 /usr/local/bin/perl5.8.8


on the other systems (all i386 archs) the allocation for these binairies 
is a lot nomalizer, think about 52440K / 41492K :

26322 root              2   0 52440K 50040K poll     0:19  0.00%  0.00% perl5.8
26296 root              2   0 52340K 49964K poll     0:20  0.00%  0.00% perl5.8
26411 root              2   0 52328K 50024K poll     0:25  0.00%  0.00% perl5.8
69338 www              18   0 41492K 35560K lockf    2:00  0.00%  0.00% httpd
69387 www              18   0 29856K 23992K lockf    1:48  0.00%  0.00% httpd
69376 www              18   0 29816K 23940K lockf    1:49  0.00%  0.00% httpd


Stripping the configs so that there is almost nothing in there , the 
allocated mem size still remains 150Mbs..

The only big diff in this case is the AMD64 arch.

The packages are default builds from port.

Anyone any ideas ?

Thanks in advanced.
