Author Topic: Transmitting large result from Node to Client uses only a fraction of bandwidth  (Read 109 times)

Hi,

I am using JPPF in my test scenario to run one calculation job with one task on a driver with a local node. The task result is a few hundred megabytes large. When the task is finished and the result downloaded by the client, the available bandwidth (around 22 megabytes per second measured via sftp to the host) is only utilized in a fraction of around 1-2 megabytes per second. Any idea what settings can influence the result download speed? Or do I have to use some other framework for faster transmission of large results and let the task result only coordinate the connection rendezvous?

Best regards,
subes

Well, I finally worked around this issue by relaying the results over a private ftp server. Even though the data operations are more with this, the actual bandwidth utilization is a lot higher and thus the results transmitted a lot faster.
