+ 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).
