MTOM taking more time than base64 method
We are migrating our WSE 2 based [File Transmitting Solution] to MTOM based, in order to provide support of big file transfer in less time. Message size using MTOM is decreased up to 20% because of different of size between binary and base64 transfer. But processing time is much higher on both server and client. And again we reach at same point where overall time of whole file upload process is higher than our old base64 based method. For every transfer, wse3 is taking extra time (upto 10 secs on each request) on file upload upto 7 MB.
Seems like it is because of converting binary to Base64 for generating digital signature
Is there any way through we can avoid this whole security process. Because of our application nature, processing time and transmit size is more important for us instead of message security.
