*puts on lab coat*
Here's some testing i spent all day doing:
1. Set up OS maxmem=600, pagefile=515~512 and registry large system cache etc. Set WIndows to run in Diagnostic Mode.
2. Set up CDT-IV folders and files. I created the files using 1024x1024x632=662700030. Didnt have enough room on the OS partition, so ran all test copying the files between the SuperPI partition and a data partition. Rar the 3 CDT files into a single uncompressed .rar of size 1.85Gb.
3. Reboot, let idle a while and check taskmanager (picture below). Then perform the CDT copying of .rar file from SuperPI partition to other partition 3 times (rest inbetween each until available memory settles), each time renaming the .rar so i dont replace files. After CDT check task manager again and see 5xxxxx / 5xxxxx .
4. Run 3 CDT tweaked SuperPI (reboot between each) and compare to 3 pre-tweaked runs i did earlier (no reboot between each)
Untweaked:
1. 14m 37.078s
2. 14m 36.188s
3. 14m 35.797s
CDT-IV:
1. 14m 27.985s (think this run was not done properly)
2. 14m 27.891s
3. 14m 27.922s
Compare then to Hipro5's 4Gb "CW" (i dont know how to do proper CW so just did a 4Gb.rar file from a partition to the SuperPI partition.
1. 14m 28.094s
2. 14m 28.109s
3. 14m 27.859s fastest run of the day
6. Graph all results and analyse loop times (time that each loop took). Find that both CDT and CW gave exactly the same characteristics.
OPB, can you please give me some pointers on anything in the above that would cause CDT to not give a better boost than just copying across a single large random file.
I even tried "balance method" where after doing CDT out of the SuperPI folder, i then returned all 3 files back into the SuperPI folder and my time was 1s slower, although both my Available and System Cache were higher (but balanced).
