Without open_file_cache:

ab.exe -k -n 10000 -c 1 http://127.0.0.1/
Requests per second: 2424.24 [#/sec] (mean)
CPU load: about 68%

It seems that CreateFile() is really heavy syscall: using open_file_cache
increases twice the number of requests. In this case nginx saves 4 syscalls:

*) CreateFile() while index files testing,
*) and CreateFile()/GetFileAttributesEx/CloseHandle().
