+         By increasing the buffer size above the default of 1K,
+         proftpd reads and writes data in larger chunks, and makes
+         fewer expensive system calls. Use of this option to set buffer
+         sizes of 8K or more has been reported to drastically increase
+         transfer speeds (depending on network configurations).

+         0 uses the default size of 1024.
