[Seaside] Mac Image Broken?

[Ted Wrinch]

Hi Sven,

It was the one-click, all in image from the Seaside site: see the link '' 'Seaside One-Click Experience 3.0.5  at http://www.seaside.st/download/pharo?_s=f6qFOGN_O20lpSoB&_k=TF27rUzr&_n&26. The VM is part of the one-click and I believe is the 'Seaside.app/Contents/MacOS/Squeak VM Opt' file - I'm not quite sure what it is as the Mac thinks it's a text file, and not a Unix binary or shell script. The ab command was 'ab -c50 -n1000 "http://127.0.0.1:8080/javascript/jquery-ui"', and it fails after posting 400 packets or so. I think that the use of the loop back address means that it can't be using DNS. My guess, from some of the older list comments, was that perhaps this VM is still built using polling for events, rather than handling them on interrupts, which could explain packet loss and suggest an inefficient UI loop.
