It seems that I have to be more clear on my problem with GST.

1. To Janko, for squeak+swazoo case, I make it sure that the simple
helloworld.html(MyResource) example runs well but this case uploading
performance is the issue.

2. To Paolo, for gst+swazoo, I even cannot run above simple helloworld.html
example. If I can get any meaningful result from ctrl+c when gst.exe takes
100% cpu from web browser request(in fact simple telnet I can make this

Thank you very much for your interest and kind support.

I just responded to Swazoo mailing list and the reason is probably the
same on all Smalltalks: generating a lot of small garbage, so that GC
has a plenty of work. We need to optimize POST streaming parser then an
upload performance should be similar to the download one.

Paolo, by the way, did you do some benchmarks on GST already?
