SSE messages delay

[ECC23]

SSE messages are not transmitted seamlessly, they are only transmitted when the buffer is full. The same application used in chrome desktop works fine but with phpdesktop does not launch the SSE messages immediately message to message.... is as if the cache despite being disabled in php.ini and use the flush and ob_flush

I noticed this once with the ssl test. Are you able to debug the issue? Is it issue with PHP CGI or Mongoose web server, or Chrome browser embedded?

This probably happens because of the 8192 bytes output buffer defined in mongoose.c file. You have to fill the buffer using something like str_pad and call ob_flush() after.

Buffer in mongoose is defined here:

I don't see any configuration options for this behavior: https://github.com/cesanta/mongoose/blob/04fc209644b414d915c446bb1815b55e9fe63acc/UserManual.md

Mongoose is written in C and code changes require significant effort.

We use an old version of Mongoose revision 04fc209644b414d915c446bb1815b55e9fe63acc which is MIT licensed. Newer versions use GPL.
