FileCatalyst Automatically Optimizes Some Client Configuration Settings

Note: This article assumes that the transfer mode is set to UDP, since the parameters discussed below can only be configured using this mode.
INIFC command: , #senderThreads=5, #blockSizeBytes=4369070, packetSize=1006, fileSize=2621404000, dataPort(s)=0, congestionControl (true=1)=1, fileID=-1915133686, Mode (ftp=1,HTTP=3,UDP=4)=4, compression (true=1)=0, compression level (0,1-10)=6, comp strategy (always 0)=0, MD5 on-the-fly (true=1)=1, congst aggression (1-10)=10, #sender sockets=1, congst strat (RTT=0,Loss=1)=1, #receive sockets=1, compress mode(zip=0,LMZA=1)=0, verify mode(after=0,concurrent=2,partial=3)=0, task priority=5
In the example above, you can see that the Block Size does not match the value that is identified in the INIFC command.
For example, if you set a block size of 4096000, FileCatalyst will actually round that value to be close to an exact multiple of the file size being transferred. This is done to optimize the transfer and reduce the need for block padding.
Another example, if the number of sender sockets exceeds the number of sender threads, the sender threads are increased to match the number of sockets. This optimizes the use of the allocated sockets for better performance.
FileCatalyst Direct Suite v3.7.3 and newer.
Since the optimization takes place behind the scenes there are no other modifications needed to enable this feature.
If this is a feature that needs to be disabled in the HotFolder the sites.xml file contains a value called OptimizeBlockSize and this value should be set to false. When making any changes to the FileCatalyst HotFolder, turn off the service and make a backup of the sites.xml file before making changes.
FileCatalyst TransferAgent Express
This application optimizes the Block Size automatically in the background and can not be configured through the UI.
