Troubleshooting Slow File Transfer Speed
File transfer speed can be affected by number of factors, including the CPU power of your client and server systems, available bandwidth for transfers, and latency in your network. In most cases, you'll see the best performance using the Reflection for Secure IT default settings. In some cases, the following settings may affect transfer speeds.
Check compression settings
You can configure compression on both the client and server using the Compression keyword. You can specify compression values 0-9. The default value for the server is 6. The default value for the client is 0. Increasing the value increases the amount of compression. Using higher values results in the use of less network bandwidth, but at the cost of more CPU cycles.
Check smart copy and checkpoint resume settings
Smart copy and checkpoint resume help minimize the amount of time spent repeating unnecessary transfer of data. These features use a series of hashes sent between the client and server to determine if part or all of a file is identical. Identical content is not transferred. This functionality is enabled by default. If you transfer files in a high latency network, the time required to send the hash values across the network can cause delays that exceed the benefit of using these features.
Check High Performance Network (HPN) settings
Reflection for Secure IT supports HPN features that maximize file transfer performance. This functionality is enabled by default.
Note: Transfer speed improvements from enabling HPN on client and server are most noticeable in networks with high latency and high bandwidth.
