[Swift-devel] Re: Another performance comparison of DOCK

[Ioan Raicu]

There are 6K jobs... how long would it take Swift to unroll a for loop 
with 6K iterations, and prep things to start sending these jobs to the 
falkon provider?  For example, doing a for loop with 6K sleeps in a for 
loop, how long does that take to start?  In this case, its more like 6K 
jobs, but 12K input files, so perhaps the 12K input files and checking 
dependencies between them (although there are none to be found) is what 
takes some time.  I vaguely remember doing 32K or 64K sleep jobs from 
Swift, and having it take at least minutes, maybe more to start up and 
have activity showing up in Falkon...
