thanks for the comments. I understand all.
Could you please clarify this:
"*Technically, it would be possible to write a Zn handler that can accept a
large upload in a streaming fashion (and save it to a file for example),
but I don't think that will happen with Seaside - so you will pull that all
Is there a chance to create a streaming solution? Is it documented
somewhere? Why do you think it won't happen with Seaside? Is there a
Seaside set or design limitation?
Answering on how it goes:
20 - 40 - 10MB upload in seconds. Now it seems to stuck on a ~ 120 MB
upload. Pharo memory (windows OS) seemed to grow ~ 441 MB. "*Space is low*"
warning window appeared. I've clicked on "Proceed" just for curiosity but
no reaction in the Pharo gui... hmmm...
