Re: [Condor-users] slow scheduling of dagman jobs

100 separate calls takes about 11 seconds

$ time for i in $(seq 0 99); do condor_submit grab1.sub>/dev/null; done  
real    0m11.257s
user    0m6.597s
sys     0m2.237s

multiple tests resulted in pretty similar time results,
real    0m11.235s
real    0m10.812s
real    0m11.000s
real    0m11.103s

So an average of about 9 jobs/sec, which is faster (but only a little) than submitting through dag.  What kind of rates are you guys getting?  Maybe this is this normal?

But if that is the case, that this is just the overhead of submitting individual jobs, why don't I see the same overhead when submitting 100 separate jobs through a non-dag submit?  What is the difference between submitting a dag file that has 100 entries and submitting a non-dag file that has 100 job submissions (not through queue 100, but through 100 separate job definitions in the file.)  I would expect those to have pretty much the same overhead.

There are some optimizations that take place when submissions are combined into a single submit file, even if many separate queue statements are used.  It would be good to test 100 separate invocations of condor_submit in your environment.
