PHP 脚本不断执行 mmap/munmap

Question

我的 PHP 脚本包含一个循环，它只不过是回显和取消引用指针（如 $tab[$othertab[$i]]-> 中的内容）。

直到昨天，这个脚本开始变得非常慢（比以前慢了 50 倍）之前，它一直工作得很好。

使用 strace 后，我发现 90% 的情况下，脚本会执行 mmap/munmap。 这是 strace 日志的随机部分：

mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000
munmap(0x7fac0156c000, 266240)          = 0
mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000
munmap(0x7fac0156c000, 266240)          = 0
mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000
munmap(0x7fac0156c000, 266240)          = 0
mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000
munmap(0x7fac0156c000, 266240)          = 0
mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000
munmap(0x7fac0156c000, 266240)          = 0
mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000
munmap(0x7fac0156c000, 266240)          = 0
mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000
munmap(0x7fac0156c000, 266240)          = 0
mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000

mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000
munmap(0x7fac0156c000, 266240)          = 0
mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000

mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0156c000
mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac0152b000
mmap(NULL, 266240, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x7fac014ea000

这是 strace -c 命令的结果：
