Buffer Size: Buffer Size is the size (in bytes) of the memory block used by the program when reading files. The default is 102400. The lowest value permitted is 32768. In most cases you should leave this setting at the default. This setting is primarily used to speed up searching in combination with the Stop Processing After First Hit in File switch or the special registry switch - Num Buffers To Process. In most other cases setting this field to a lower or higher value will NOT result in faster searching. Low values may actually increase search time because the program will have to perform more separate file reads on a given file.
