Performance comparison of PHP three accelerators

Performance comparison of PHP three accelerators

Hardware environment:

Server: Dl180g6 (Intel (R) Xeon (r) CPU E5620 @2.40ghz) 16G memory

Presses: Dl180g6 (Intel (R) Xeon (r) CPU E5620 @ 2.40GHz) 16G memory

Software Environment:

nginx1.2.5php5.4.9 Max 600PHP-FPM

network environment: Gigabit

Test scenario:

Scenario One: (without any extensions):

Scenario Two: (Open APC 3.1.14, allocate cache 512M):

Scenario Three: (Open XCache 3.0.1, allocate cache 512M):

Scenario Four: (Eaccelerator 1.0-dev, allocation cache 32M): because the failed to setthe 1.15m, the test page generates a cache that is less significant.

The above four scenarios, the same number of concurrent users 20 (is the best number of users), access to the same URL (http://playback.i.ifeng.com/hehe.pi?vt=5), each scene runs for 5 minutes, Compare the performance of three kinds of PHP caches under the same pressure.

Test results:

Extended	CPU (Us/sy)	Load Average	Response Time (s)	qps/s
None	67%,26%	12	0.18	108
XCache	56%,34%	15	0.16	120
Eaccelerator	64%,27%	15	0.13	150
Apc	60%,30%	13	0.11	170
