I knew why. i turn on error log with level debug. I have found that each request will first visit the cache .
I guess io is higher because each visit to read and write caching . so i set proxy_buffering off and proxy_store off, then everything is ok.

主题： load balance -- Write IO is too high
i have two servers, and 1 server as proxy server and upstream 1 server and 2 server.
I set up 1 server's weight is 1, and 2 server's weight is 5 .
Now they can work properly , but 1 server's write IO is too hight .
Applications is no write operation , Why such a high level of write IO ?
Thanks very mach. Sorry for my bad english
