Hello Hadoopers, I was reading the hardware recommendation doc. from Cloudera/HP, and this is one of the recommendation about CPU.
"To remove the bottleneck for CPU bound workloads, for the best cost/performance tradeoff, we recommend buying 6 core processors with faster clock speeds as opposed to buying 8 core processors." Yes, my application is heavily using CPU than IO, but isn't that we need more cores --> more slots (yes..with enough memory) more computation slots. My gut feeling doesn't tell me that 6 core with faster clock would deliver more horse power than 8 cores. I guess because it said "cost/performance". What do guys think? Thanks in advance Patai
