When hosting the FileCatalyst Server on Amazon Web Services (AWS) - EC2 instances, S3 buckets can be added to the FileCatalyst Server as an external storage device. Amazon provides libraries that we have used to integrate this storage device into the Server where we can read and write to this endpoint.
In FileCatalyst Server v3.6 beta 27, when the Security Group on the EC2 instance is set to allow all IPs the transfer experiences some packet loss and when our congestion control algorithm tries to recover from the packet loss it causes a reduction in the bandwidth in some cases the transfer comes to a halt. The symptoms of the increase in Packet Loss and decrease in Bandwidth happen simultaneously and are visual indicators of issues transferring files into the EC2 deployment.
Our Engineers are currently working with the latest AWS drivers to resolve this issue and improve the performance to reading and writing to S3 buckets.
FileCatalyst Server v3.6 and newer.
