*Parallels Virtuozzo Containers shows the best network throughput over all the solutions tested
*In Receive performance test (physical client-> VM/CT) Parallels Virtuozzo Containers shows great benefits over hypervisors: x2 Times faster than ESXi4.1 and x5 Times faster than XenServer5.6
== LAMP Stack ==
=== Benchmark Description ===
LAMP (acronym for Linux, Apache, MySQL, PHP) software stack is widely used for building modern web sites. We measure not only performance (how many requests can deliver server), but also maximum response time - to understand QoS.
=== Implementation ===
To measure LAMP software stack performance and density we use DVD-Store E-Commerce benchmark developed by [http://linux.dell.com/dvdstore/ Dell].
=== Testbed Configuration ===
Server: 4xHexCore Intel Xeon (2.66 GHz), 64 GB RAM, HP MSA1500 SAN Storage, 8 SATA (7200 RPM) Disks in RAID0
Client: 4xHexCore Intel Xeon (2.136 GHz), 32 GB RAM, Intel 82598EB 10-Gigabit network card
Network: Gbit 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:
* Each VM/CT was configured with 1 vCPU, 1 GB RAM
* Small db was deployed from DVD Store samples
* Dvd Store benchmark client run string: ds2webdriver.exe --target=172.0.1.%VM% --think_time=0.05 --n_threads=3 --warmup_time=10 --run_time=10 --db_size_str=S --n_line_items=1 --pct_newcustomers=1
* Firewall was turned off
* All other tunings were left at default values
=== Benchmark Results ===

=== Summary ===
* Parallels Virtuozzo Containers shows the best performance over solutions tested: PVC 38% faster than XenServer and more than x2 times faster than HyperV and ESXi
* Parallels Virtuozzo Containers shows the best response time over solutions tested: PVC has 33% better response time than ESXi and x2 times better response time than XenServer and HyperV
