Hi David,

I tested a 49 mb file; using the older buffer it took 15 minutes or more.

The 64k buffer took 20 seconds or less.

An 8 mb file took 3 seconds.

I'll add a Jira and update the buffer size in the next release.

Thanks for pointing out the slow speeds!

Okay, thanks!

I see now that the buffers size is very small.  (4096 is small for very large files.)

Yes.

Although in iACS I'm using the upload menu function.
