I'm using the SFTP client to upload large files to a server. This particular server has a limit on the number of transactions per second, therefore, I would like to have as large a chunk as possible to get the most out of each transaction.

But no matter how I set the buffer sizes (UploadBlockSize and SftpBufferSize), the chunks are always 32K. This is what I see in the OnProgress handler.

How do I truly increase the size of the buffers so I can maximize my throughput?

SBB 11.0.245 and 11.0.248

Regards,
Ron

Hello Ronald,

Please set AutoAdjustTransferBlock to false to make the component get use of your custom block size values.
