Re: Transfer Large binary data from client to server uses too much heap memory

I struggled with this issue a while ago, and the limit is Java itself.
Can't remember preceisely where, but the the runtime uses buffers in a
naive way that basically results in buffer memory being copied. Using
out of the box URLConnections the limit seems to be about 10mb. I had to
write my own socket-level code to get large files working (largest
transferred so far is 700mb CD ISO).
