NodeJS ECT Slow rendering

[Deleted user]

Hi i have simple code that i will render:
150 x FOO.

When i render it with Node.js template (ECT) the response time is: 1855ms
With PHP response time is: 24ms

ECT code:

<?- "FOO"; ?>
<?- "FOO"; ?>
<?- "FOO"; ?>
<?- "FOO"; ?>
<?- "FOO"; ?>
...

PHP code:

<?php echo 'FOO'; ?>
<?php echo 'FOO'; ?>
<?php echo 'FOO'; ?>
<?php echo 'FOO'; ?>
<?php echo 'FOO'; ?>
...

All are no cached.
And how bigger the count the slower becomes NodeJS (ECT)

Is there something that i miss?
