Subject Does the scan speed with CL.ALL is faster than CL.QUORUM and CL.ONE?
Date Wed, 25 Aug 2010 06:52:26 GMT
Hi all,

I ran my benchmark(OPP via get_range_slices) and found the following:
Why does the scan speed with CL.ALL is faster than CL.QUORUM and CL.ONE?

CL.ONE (1k per row, Count:50000)
scan :11095 ms
scan per:0.2219 ms
scan thput:4506.5347 ops/sec

CL.QUORUM
scan :11072 ms
scan per:0.22144 ms
scan thput:4515.896 ops/sec

CL.ALL
scan :7869 ms
scan per:0.15738 ms
scan thput:6354.0474 ops/sec

Thanks.

Shen
