[Seaside] Re: What alternative for fileUpload with WAFile for large files?

[Van Upboy]

Hi Goran,

I installed your changeset (I don't quite know what you changed, but it
seems to work).

These are the times on Windows Vista for some files:

Time: 0.053 Size: 211.414 MB/s: 3.804152866579452
Time: 8.257 Size: 17.342.200 MB/s: 2.003004811672577
Time: 220.436 Size: 253.131.539 MB/s: 1.095125330783933

The larger the file, the slower it gets. I would expect it the other way
round.
I didn't test the async version, because you seemed to suggest that it
didn't improve things for large files.
The other thing I notice is that the seaside upload test doesn't come back
with the file information when it is finished. Is that expected behavior?

Do you know why your changes aren't incorporated into pharo? To me it seems
a wise tactic to use memory as buffering, instead of trying to store it all
in memory.

Regards,
Van.
