After my previous thread, I think I found out what causes the long delays.
I run this program on several Linux computers, and the sometimes (after the file with the arrays becomes big) the fwrite takes between 100 ms to 900 ms.
This is very bad for me, as I want a timer to halt each 30 ms.... ... (5 Replies)

STREAM_SET_WRITE_BUFFER(3) 1 STREAM_SET_WRITE_BUFFER(3)
stream_set_write_buffer - Sets write file buffering on the given stream
SYNOPSIS
int stream_set_write_buffer (resource $stream, int $buffer)
DESCRIPTION
Sets the buffering for write operations on the given $stream to $buffer bytes.
Output using fwrite(3) is normally buffered at 8K. This means that if there are two processes wanting to write to the same output stream
(a file), each is paused after 8K of data to allow the other to write.
PARAMETERS
o $stream
- The file pointer.
o $buffer
- The number of bytes to buffer. If $buffer is 0 then write operations are unbuffered. This ensures that all writes with fwrite(3)
are completed before other processes are allowed to write to that output stream.
RETURN VALUES
Returns 0 on success, or EOF if the request cannot be honored.
EXAMPLES
Example #1
stream_set_write_buffer(3) example
The following example demonstrates how to use stream_set_write_buffer(3) to create an unbuffered stream.
<?php
$fp = fopen($file, "w");
if ($fp) {
stream_set_write_buffer($fp, 0);
fwrite($fp, $output);
fclose($fp);
}
?>
