FWIW we had i/o problems with execute nodes untarring several large
tarballs at once. I added /etc/cgconfig.d/condor.conf

group htcondor {
    cpu {}
    cpuacct {}
    memory {}
    freezer {}
    blkio {

# 100MB/s
#
        blkio.throttle.write_bps_device = "8:0 104857600";
    }
}

and those problems seem to have gone away.

This is on centos 7, "stable" condor.
