Parallel Chunk Uploads
Upload several chunks of the same file at once to make better use of high-bandwidth connections. This demo uses the current chunkConcurrency option while still accepting the older alias in the core library.
What you should see: chunks uploading in parallel instead of sequentially, which is usually where the speed comes from on a fast connection. Use a file well over 2 MB to see more than one chunk.
Choose a large file to compare chunk throughput.
CoreUpload.create('#parallel-uploader', {
uploadUrl: '/api/upload/upload',
chunkUrl: '/api/upload/chunk',
chunked: true,
chunkSize: 2 * 1024 * 1024,
chunkConcurrency: 3,
autoUpload: true
});
