retest the paging file settings and took the time to get more pictures this time.
i pushed all of paging file all the way up to limit several times then i use the disk defragmenter to analyze all of partitions that the paging files are in.
the system paging files usage were went all the way up to the end of the limit that i've set them, then went all the way down to about the operating system idles and then went way up again...
and then after many hours later i tested them again..
as i can see that the x64-based versions of the Windows XP Professional has improved quite a lot on how it handles the paging files, paging files addressing and the overall memory management.
all of the running in background programs (include anti-virus's file system monitors) have never been turned off. all of the applications were still running quite smoothly which i won't see this in Windows XP x86-32bit.
the size of the paging file have never went beyond the limit (this should be the same as the 32-bit version), but the x64 system still showing like it had quite a bit memory left and kept going on with my test using the RAM that are on the system.
with the 32-bit version, it would show some lacks on the Windows performance, and also as i've seen before on the same system with same applications setups that it can only take around two-thirds and sometimes just a bit pass halfway then a wanning from an application or Windows itself about the system has low memory would turn up.
Paging file fragmentation??
all of the paging files are still in one piece and there are no fragmentation in the files.
