Then I increased the concurrency:

ab.exe -k -n 10000 -c 500
nothing error

 ab.exe -k -n 10000 -c 1000 
Error.log: many lines of "2009/04/22 11:14:15 [alert] 2744#448: *951 WSARecv() failed (10053: Your software in this host abandons this connection.) while keepalive, client: 127.0.0.1, server: 0.0.0.0:80"

(note: The error.log contains some Chinese characters after error number 10053 because of my OS's location. I translated these into English, maybe not accurate.)

My testing index.html is 151 bytes. Maybe it's too small. Then I used a test.html with size of 1K bytes. The result changed:

ab.exe -k -n 10000 -c 50
nothing error

ab.exe -k -n 10000 -c 100
nothing error

ab.exe -k -n 10000 -c 200
Error.log: many lines of "2009/04/22 11:34:22 [alert] 2744#448: *4806 WSARecv() failed (10053:Your software in this host abandons this connection.) while keepalive, client: 127.0.0.1, server: 0.0.0.0:80"

Then I tested a 100k file:

ab.exe -k -n 10000 -c 5
nothing error

ab.exe -k -n 10000 -c 10
nothing error

ab.exe -k -n 10000 -c 20
nothing error

ab.exe -k -n 10000 -c 30
Error.log: 
	there are two kinds of errors:
