block cache was at default 0.2%, the id's being looked up don't repeat and each one has a lot of versions, so not expecting cache hits - also was seeing a lot of cache evictions as is. Can we get better performance in such a scenario?
Does having more discs help? or would RS be the bottleneck? Lohit: Without compression, I think we were seeing 300+ - that was with default config Memory for RS is 4GB and DataNode at 1G
