There should be no problem in Condor handling larger values for
MAX_CONCURRENT_UPLOADS or _DOWNLOADS. However, in many cases, I doubt
you will get higher throughput than when you use a lower level of
concurrency. Depends on how many disk heads the files are sitting on.
It would be nice if Condor kept track of the underlying resource
utilization, but we thought adding these two transfer queues would at
least be a good improvement over the previous solution, which was to
blindly limit the rate at which jobs start up.
I hope it helps!
