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 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
Network: Gbit direct server<>client connection
Virtualization Software: ESXi4.1upd1, XenServer5.6fp1, HyperV (R2), OpenVZ (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
- OpenVZ shows the best performance over solutions tested: OpenVZ 38% faster than XenServer and more than x2 times faster than HyperV and ESXi
- OpenVZ shows the best response time over solutions tested: OpenVZ has 33% better response time than ESXi and x2 times better response time than XenServer and HyperV
