|
* PGSZ Used in input.c as the size of "pages" to read from
|
|
* the file. Generally, smaller sizes give the opportunity
|
|
* to read less; larger sizes make the reads that happen
|
|
* more efficient.
|
|
*
|
|
* Recommendation: Use at least the block size for the most
|
|
* common file systems on the machine. Twice the common
|
|
* size seems to work well, 4 blocks seems a little too big.
|
|
* SVR3 uses 1k blocks, SVR4 uses 2K.
