  Here are some tests. May these tests are not rigorous, but they can show you my question:
    why can't I get the speed like chrome without proxy set?

  file size : 93582KB

  Box : https://app.box.com/folder/0

  operating system
     windows server 2008 R2 standard

  Test1:
  
  libcurl
    compiler: vc=8
    version: 7.57.0
    openssl: 1.0.2n
    zlib: 1.2.11

  case1:
  upload the file to Box, with libcurl: the speed is about 350KB/s;
  I tried the CURL_MAX_WRITE_SIZE: 16384, 32768, 65536, 131072, 262144, 524288, 1048576

  case2:
  upload the file to Box, with libcurl, set proxy http://127.0.0.1:3213 : the acerage speed is about 6MB/s;

  case3:
  upload the file to Box, with chrome, no proxy : the speed is about 6MB/s

  upload the file to http://speedtest.tele2.net

That's weird, I don't know what could be causing it. Does Chrome use the proxy? Can you try this PostUpload test [1] with and without the proxy?
