1. Some troubleshooting steps to perform against slow speeds
Many factors affect IBM Aspera transfer speed. Some can be addressed by IBM Aspera on Cloud users and administrators. Some must be addressed by administrators of tethered IBM Aspera High-Speed Transfer Servers. Some may be due to cloud service or network conditions that may or may not be under your control.
2. Home Network Limitations
You may experience slow transfer speeds when using Aspera on Cloud at home. Most home internet connections are slower than expected; this is particularly true for upload speeds.
There are several free apps to verify your actual internet speed. Search the web for "internet speed test" to find one. Transfer speeds can never surpass the limits of the local internet connection.
3. Connectivity Issues Test
Use this web-based diagnostic tool to help identify connection issues. This page also provides additional troubleshooting options and easy access to both the latest version of Aspera Connect should you not already have the latest version and to the Aspera Connect documentation set.
4. Slow upload in a High-Speed Environment
To troubleshoot slow upload speeds in a high-speed environment, determine whether the issue is on the client side (Aspera Connect) or the server side of the transfer.
Test the client side by transferring a large file from your desktop to the Upload folder on the Aspera Demo Server.
- Install IBM Aspera Desktop Client if you don’t have it installed: https://www.ibm.com/support/fixcentral/swg/selectFixes?parent=ibm~Other%20software&product=ibm/Other%20software/IBM%20Aspera%20Desktop%20Client&release=All&platform=All&function=all
-
Log in to the Aspera Demo Server:
- Go to Connections to view the Connection Manager. Click on + to add new Connection. Use the login below to authenticate
- Log in with user name asperaweb and password demoaspera to server demo.asperasoft.com
- Select the Connection and click “Connect”. Browse to the “Upload” path (you will see many files)
- Click Upload and select a large file. Be sure the file you upload does not contain confidential or proprietary information.In the Confirm dialog, click Allow to accept the connection between your desktop and the Aspera Demo Server. In the Activity panel that displays, click the Transfer Icon in the row of your transfer to open the Connect Transfer Monitor. The configuration on the Demo Server guarantees that the server side won't be a bottleneck. If the upload to the Demo Server is slow, the issue is most likely to be on the client side. Analyze the Connect log files to determine the cause of the slow transfer. Find logs for IBM Aspera Connect.
- If you need to create a local file you can use this command (in Mac) You can use 5G size.
-
mkfile -n 5G aspera_5G_file
5. Slow or Stagnant Transfer Speeds
When using the FAST protocol via the Aspera Connect client, it can occasionally consume the entire network capacity of the local network. This excessive usage can lead to reduced or stagnant upload speeds. Adjusting the settings of the Connect client might help mitigate this issue.
- Setting a Transfer Cap on the Connect Client:
- Click on he Preferences in the Aspera Connect client.
- Navigate to the Bandwidth Tab.
- Set a specific limit for the transfer rate and save the changes.
