No. It will normally (depends on your environment) perform slower then the openssh's sftp client (with standard libcurl i normally stuck on 800kb/s while performing 5.5MB/s with sftp client from openssh).
Quick, nasty fix for low latency high traffic networks (like 100mbit < 20ms ping) is to build curl with CURL_MAX_WRITE_SIZE around 512kb (try different variants from 256k to 2MB).

Nobody (as far as i know) has already taken actions to writes patches for libcurl / libssh2 to gain a better sftp performance.
It's on my list "needs to be done in life", .. but currently not on the top. :)
