IMHO, that's a design flaw. Regardless of whether PHP is doing buffering, it shouldn't break up blocks of static content into small pieces--especially not as small as 400 bytes. While it's certainly valid for PHP to insert a flush bucket right before a block of embedded code (in case that code takes a long time to run), breaking static text into 400-byte chunks will usually mean that it takes *longer* for the content to reach the client, which probably defeats PHP's motivation for doing the nonbuffered output. There's code downstream, in the httpd's core_output_filter and the OS's TCP driver, that can make much better decisions about when to buffer and when not to buffer. --Brian
