FIXME Vasya== Response Time == === Benchmark Description ===The aim of this benchmark is to measure how fast can application inside of virtual machine (VM) or operating system container (CT) react on external request under various conditions:* Idle system and idle VM/CT* Busy system and idle VM/CT* Busy system and busy VM/CT Described benchmark case is common for many latency sensitive real life workloads. For example: high performance computing, image processing and rendering, web and database servers and so on. === Implementation ===To measure response time we use well known netperf TCP_RR test. To emulate busy VM/CT we run CPU eater program (busyloop) inside of it. To emulate busy system we run several busy VM/CT (to eat all the host CPU time). Netperf runs in server mode inside of '''one''' VM/CT. On the separate physical host we run netperf TCP_RR test against selected VM/CT over the 1Gbit network. === Testbed Configuration ===Server: 4xHexCore Intel Xeon (2.66 GHz), 32 GB RAM Client: 4xHexCore Intel Xeon (2.136 GHz), 32 GB RAM Network: 1Gbit direct server<>client connection Virtualization Software: ESXi4.1upd1, XenServer5.6fp1, HyperV (R2), PVC 4.7 (RH6) 2.6.32-042test006.1.x86_64 Guest OS: Centos 5.5 x86_64 Software and Tunings: * netperf v2.4.5* '''one''' VM/CT with netperf in server mode configured with 1 vCPU, 1 GB RAM* '''six''' VMs/CTs (which needed to load server CPU - see testcases) configured with 4vCPU 1GB RAM* netperf run string:** in VM/CT; netperf -p 30300** on the client: netperf -p 30300 -H 172.0.1.1 -t TCP_RR -l 120 -- -r 128 -s 128* Firewall was turned off* All other tunings were left at default values. === Benchmark Results ===
