There's no direct equivalent, but CURLOPT_BUFFERSIZE is set as a side effect

curl can sometimes try a couple of different FTP modes before
finding the correct one to use which will cause a measurable slowdown on
a high-latency connection. If you know which one is usable you can have
curl use it directly (e.g. --disable-epsv, --ftp-port, --ipv4).
Something similar holds for the CWD method as well (--ftp-method), and the
Nagle algorithm can also increase latency (--tcp-nodelay).
