I found that when I select many files (e.g. around 400 jpg, 6KB per files) in AsyncUpload, the upload speed would become slower and slower. Initially, the upload speed could have around 2.4KB/s, but it gradually drops to even below 40 Bytes per second as the upload proceeds. It takes me so long time to upload a large amount of files.
Are there any configurations to improve the upload speed of multiple files ?
Thanks!
