</span>Hi Hugues,<br>
looking at your comment in<br>
<a href="https://github.com/phpmyadmin/phpmyadmin/commit/2da2c4caf" rel="noreferrer" target="_blank">https://github.com/phpmyadmin/phpmyadmin/commit/2da2c4caf</a><br>
<br>
you wanted to reduce the size of data to read, maybe to improve parsing<br>
speed?<br>

I believe that there is no performance loss or gain if the size will be increased, because the parser continues from where it left. There is a special case involving DELIMITER statements which may cause a small rewind, but it's negligible. At least, this is what the new parser does, I believe the old one did the same.</div><div class="gmail_extra"><br></div><div class="gmail_extra">[1] <a href="https://github.com/phpmyadmin/phpmyadmin/commit/2da2c4c" target="_blank">https://github.com/phpmyadmin/phpmyadmin/commit/2da2c4c</a></div><div class="gmail_extra"><br></div><div class="gmail_extra">Best regards,</div><div class="gmail_extra">Dan Ungureanu</div></div>
