.SH DESCRIPTION
Pass a long specifying your preferred \fIsize\fP (in bytes) for the receive
buffer in libcurl. The main point of this would be that the write callback
-gets called more often and with smaller chunks. This is just treated as a
-request, not an order. You cannot be guaranteed to actually get the given
-size.
+gets called more often and with smaller chunks. Secondly, for some protocols,
+there's a benefit of having a larger buffer for performance.
-This size is by default set as big as possible (\fICURL_MAX_WRITE_SIZE\fP), so
-it only makes sense to use this option if you want it smaller.
+This is just treated as a request, not an order. You cannot be guaranteed to
+actually get the given size.
+
+This buffer size is by default \fICURL_MAX_WRITE_SIZE\fP (16kB). The maximum
+buffer size allowed to set is \fICURL_MAX_READ_SIZE\fP (512kB).
