Uploader 7 Multithreaded Parallel Uploads

I have a situation where a large number of medium sized files would be uploaded using Uploader 7, and I would like to increase the overall speed of the transfer using multithreaded parallel uploads. Because Uploader 7 only uploads a file at a time, the overall speed isn't staggering.

I think I noticed in the documentation that Uploader 6 allowed you to configure multithreaded parallel file uploads. I can't find any mention of it in the Uploader 7 documentation.

Is configuring multithreaded uploading possible in 7? Was it removed? Are there other ways to increase the throughput of a large number of file upload?

Thanks!

Hello,

Thanks for taking interest in our software. Previously I wrote the article dedicated in version 7 speed and performance: Upload Speed Comparison between Image Uploader 6 and 7.

“MaxConnectionCount” feature was supported by ActiveX edition only in previous versions of the product and was available in IE browsers family. The feature worked in the following way: the uploader created multiple concurrent threads, each of them was preparing files and uploading them. We found that Windows family of operating systems has different implantations of schedulers allocating CPU time between worker threads inside a process. We had users complaining about freezing of user interface during upload process (with “MaxConnectionCount” > 1), especially Windows XP was affected with this problem. We had nothing to do with that because operating system assigned too much CPU time to upload threads and IE got stuck. That is why we re-implemented this part and left two threads working in synchronization (see the diagram in my blog post), it gives less load to IE process and works more reliable.

Also our tests shows that difference between one thread upload and 2-5 threads upload gives not so big improvement in speed but gives significant load to your server environment because you end up with 2-5 times more connections number. It stresses your server too much.
