Andriy Gapon requested any facts that demostrates or shows examples when ULE scheduler is not so good than others.

Perhaps it's not a scientific and statistically valid but, for me, it shows when is ULE under other schedulers. Also, some people has asked and pointed about using 4BSD and not ULE in 8.x because it works better for some type of workload.help
