Subject Re: [PATCH]: Counting I/O with FLUSH
Date Thu, 17 Oct 2002 05:29:02 GMT
I'm doing some testing with and without this new filter that replaces EOS with
FLUSH.

Here is the test HTML file:

---------------------------------
<html>
<img src="1.gif" />
<img src="2.gif" />
<img src="3.gif" />
...
<img src="23.gif" />
<img src="24.gif" />
<img src="25.gif" />
</html>
---------------------------------

First, the bad news - I'm using Mozilla 1.0.1, which support pipelining, but I
can't make Apache send more then one GIF per packet even when this filter is
disabled (using tcpdump to monitor the traffic). Each GIF is only 66 bytes, with
headers it turns out 183 bytes. So, it would make sense to put them all in one
packet. Unless, of course, the pipelining is not used at all when there is a
FILE bucket (I've seen something like this in core_output_filter). So, what do I
do to get this test under way? How does one "activate" pipelining in Apache 2?

Second, the good news - the payload of each packet reported by tcpdump is
identical to what mod_logio reports. Hurray!
