Fix the size of your
vcache. The Win95 OS attempts to cache data recently read from disk in the
computer's RAM. The next time Win95 gets a request for this data it does
not need to pull it from the computer's hard disk. Rather, the data is now
available via the computer's RAM -- a much faster type of data storage. In
theory, disk caching will boost the computer's performance. By default
Win95 dynamically allocates RAM for disk caching, and this can be
problematic. When Win95 runs out of RAM to use for disk caching, the
Virtual Memory Manager takes over and begins swapping data back out to
disk, to what is called the "swap file." At those moments when the Virtual
Memory Manager begins swapping the disk cache back to disk, access to both
the hard disk and RAM is delayed and any pending data requests are
interrupted. This redundant data caching can affect timing dependent
operations such MIDI Time Code (MTC), digital audio, and digital video.
The results can be audio drops, dropped video frames, and MTC stuttering.
To stabilize the Win95 disk caching scheme, we simply need to set the disk
cache (vcache) to a fixed size. Here's how: Now, add the following
to the SYSTEM.INI file, found in C:\WINDOWS: |
