easy:SetOpt_BufferSize(size)
size
(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. Secondly, for some protocols,
there's a benefit of having a larger buffer for performance.
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 #CURL_MAX_WRITE_SIZE
(16kB). The maximum
buffer size allowed to be get is #CURL_MAX_READ_SIZE
(512kB). The minimum
buffer size allowed to be get is 1024.
