Dear all,

I want to test the performance of an application and relate the time it took to execute a request with the number of bytes sent from the server to the client.

I have seen the %b log option that gives me the number of bytes that went from the client to the server. Now I am looking for the other way around.

thanks for helping me.

No.

%...b Size of response in bytes

That is for both ways, from server to client and client to server, depending upon the request method.

But, with mod_logio you have two additional flags:

%...I Bytes received
%...O Bytes sent

Thanks,
good advice, works perfectly.
