That doesn't make sense. My CPU is a 4 core i5 with 3.4 GHZ. Do you think blockland might only be using 1 core?
That's weird, it says you have 1,801mhz which is 1.8ghz. When I click on my 3DMark 11 link it says I have 3,298mhz which is 3.20ghz, I usually have 3.10ghz as normal but turbo boost can bring it up to 3.4ghz so I am guessing this IS accurate. Did you underclock your CPU or something? Blockland does use one or two cores, it uses Core number 4.
