Andriy Gapon requested any=20 facts that demostrates or shows examples when ULE=20 scheduler is not so good than others. The images=20 shows how the 3 schedulers performs with the same=20 workload when number of cores is changed. Perhaps=20 it's not a scientific and statistically valid=20 but, for me, it shows when is ULE under other schedulers. Also, some people has asked and pointed about=20 using 4BSD and not ULE in 8.x because it works=20 better for some type of workload.
