[Swift-devel] too much slow down.

[skenny at uchicago.edu]

so andric and i have been doing lots of runs the past week 
with the latest swift. we've definitely noticed a lack of
errors from swift. that is, when it can't get a job thru it
hangs...often for hours 'til we kill it.

yesterday my job hung for about 20min so i
killed it and tried running it with the previous version of
swift. right away i got an error saying that the job was
having trouble creating a directory on the remote site (which
was in fact a correct error, there was a problem with the
permissions).

my personal vote would be for faster failures. i guess it's
also worth mentioning that we rarely (read: never) run
multi-site...mostly bcs we need to separate debugging our
workflows from debugging our sites :)
