NAME
CURLOPT_BUFFERSIZE - receive buffer sizeSYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_BUFFERSIZE, long size);
DESCRIPTION
Pass a long specifying your preferred 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 is a benefit of having a larger buffer for performance.DEFAULT
