Round 6 - InfRC - (generated with code version - commit 24f6d2)

• New cluster with 36 nodes total used.
• master/coord at rc01.rccluster. clients on all other nodes - rc01-36.rccluster
• latency and throughput curves measured for different objects sizes read under load (both quantities are measured in the same experiment)
• only reads are measured - single object within a single table is read
• Object sizes at 100, 1000 and 10000 bytes

• transport=infrc, Throughput versus load

• transport=infrc, Latency versus load

Round 5 - InfRC - (generated with code version - commit 24f6d2)

• New cluster with 33 nodes total used.
• master/coord at rc01.rccluster. clients on all other nodes - rc01-36.rccluster
• different objects sizes
• load vs time-per-operation measurements only.

• transport=infrc, Operations per second (throughput) versus load with 1000 byte objects
  Image Added

• transport=infrc, Operations per second (throughput) versus load with 100 byte objects
  Image Added

Round 4 - InfRC - (generated with code version - commit db388ad3)

• Reference measurement - Steve's access of 100 byte objects on single server - 7000 ns
• Single server round trip time - 100,000 measurements - 100 byte objects in 4833 ns run-bench script
• No load - 100,000 measurements - master/co-ord on rc01, client on rc02 - 100 byte objects in 5109 ns run-perf script
• No load - 10,000,000 measurements - master/co-ord on rc01, client on rc02 - 1000 byte objects in 5093 ns run-perf script
• 10.0.0.x NICs were used.
• 1 hour passes - cluster is as idle as the last experiment. But.....
• Single server round trip time - 100,000 measurements - 100 byte objects in 9869 ns run-bench script
• No load - 100,000 measurements - master/co-ord on rc01, client on rc02 - 100 byte objects in 9878 ns run-perf script

• transport=infrc, Operations per second (throughput) versus object size
