    APM vs APCI W2K

    Hi

    I would like to know if it makes any difference to performance depending if I installed Windows 2000 in APM mode rather then ACPI? Does ACPI consume more memory than APM?

    Thanks

      well... IF your motherboard BIOS implements ACPI 100% according to specs, then ACPI has the following benefits:
      - Hibernation support in win2k
      - No more IRQ troubles: all PCI devices all share the same IRQ
      - Improved Power Management
      - other stuff I can't remember/don't know about.

          In THEORY (mind you only in theory) ACPI is a teensy bit slower because the OS does arbitration of devices. However, this speed loss is more than made up for by lack of device contention, and the fact that no device can ever fire off an IRQ than hangs the system or slows down the system.

          So ACPI is better but no faster or slower...

          Unless the hardware is built around ACPI, in which case it is faster.

              OK, I have one more question about Windows 2000.

              What is faster, running NTFS or FAT32?
              I currently have 7 partitions, two are FAT16, one is NTFS and the rest is FAT32. I have Windows 2000 installed on a NTFS partition.

              What gives better performance?
              I know that NTFS supports stuff like encrytption and built in compression but I would like to know about speed.

              Also, is it better to have the paging file on a NTFS or FAT?

              Thanks....

                  I'm aware of the benefits of ACPI, but since I have an old AT power supply I don't need hibernation and such stuff. It's enough that it turns off the monitor when needed.
                  What I would like to know is there any benefit in performance if using ACPI over APM and memory usage. I currently have it installed in ACPI.

                      People will argue with me, but with modern hardware (drive controllers and drives), NTFS is much faster, more stable, and less prone to complete-and-utter-your-hard-drive-is-screwed-fragmentation.
