Set your error log level which will write warnings as a minimum.
Other words, be sure warnings are being printed to your error log.

Set your buffer to a logical standard issue size, 4096 bytes.
Test your server, look at your error log.

Increase your buffer to a common multiple of 4096, maybe 32768 bytes.
Test your server, look at your error log.

If there is a problem with Apache, this "should" show up in your
error log as a warning. Note that is "should" show up. You might
try a deliberate misconfiguration which prints a warning to verify
warnings are being printed via your Win32 configuration.

Research documentation about warnings to find examples.

If not, you may have issues with your Win32 sock. Your sock
configuration might be buffering, then sending 4096 bytes.

Below you will find the code for this, and how an error is handled.

I would first test Apache to be sure byte size is being set.
Then I would look at configuration for your sock to discover
if there are issues. There are variety of settings you can
change for Win32 sock applications.

Remember, you have to restart Apache to effect httpd.conf changes.

Purl Gurl

This code "might" not be the same for your version,
but this will give you an idea of what to look for in
your error log; failed to set ... etc

if (send_buffer_size) {
stat = apr_socket_opt_set(s, APR_SO_SNDBUF, send_buffer_size);
if (stat != APR_SUCCESS && stat != APR_ENOTIMPL) {
ap_log_perror(APLOG_MARK, APLOG_WARNING, stat, p,
"make_sock: failed to set SendBufferSize for "
"address %pI, using default",
server->bind_addr);
/* not a fatal error */
}
