XCache v1.2.2
配置
extension="xcache.so"
[xcache.admin]
; Change xcache.admin.user to your preferred login name
xcache.admin.user = "admin"
; Change xcache.admin.pass to the MD5 fingerprint of your password
; Use md5 -s "your_secret_password" to find the fingerprint
xcache.admin.pass = "e10adc3949ba59abbe56e057f20f883e"
[xcache]
; Change xcache.size to tune the size of the opcode cache
xcache.size = 24M
xcache.shm_scheme = "mmap"
xcache.count = 2
xcache.slots = 8K
xcache.ttl = 0
xcache.gc_interval = 0
; Change xcache.var_size to adjust the size of variable cache
xcache.var_size = 8M
xcache.var_count = 1
xcache.var_slots = 8K
xcache.var_ttl = 0
xcache.var_maxttl = 0
xcache.var_gc_interval = 300
xcache.test = Off
xcache.readonly_protection = On
xcache.mmap_path = "/tmp/xcache"
xcache.coredump_directory = ""
xcache.cacher = On
xcache.stat = On
xcache.optimizer = On
[xcache.coverager]
xcache.coverager = Off
xcache.coveragedump_directory = ""
结果
4539 fetches, 50 max parallel, 1.04079e+07 bytes, in 300 seconds
2293 mean bytes/connection
15.13 fetches/sec, 34693.1 bytes/sec
msecs/connect: 0.405883 mean, 0.999 max, 0.182 min
msecs/first-response: 3214.64 mean, 18691.3 max, 772.952 min
HTTP response codes:
  code 200 -- 4539
No OP-Cache
结果
1798 fetches, 50 max parallel, 3.9867e+06 bytes, in 300 seconds
2217.3 mean bytes/connection
5.99332 fetches/sec, 13289 bytes/sec
msecs/connect: 12.0802 mean, 2999.48 max, 0.203 min
msecs/first-response: 6966.64 mean, 59754 max, 381.002 min
41 timeouts
61 bad byte counts
HTTP response codes:
  code 200 -- 1757
结论:
eAccelerator 0.9.5.3
25.2266 fetches/sec
APC 3.0.19
24.3433 fetches/sec
XCache v1.2.2
15.13 fetches/sec
No OP-Cache
5.99332 fetches/sec
eA的效果最好.APC紧随其后.两者的性能表现基本相同.xcache最差.
