Custom/Defuse\Crypto\Core::pbkdf2 really slow

[slaroy]

I am trying to analyze performance on my webpage using Newrelic. One of the slowest parts of the page is consistenly Custom/Defuse\Crypto\Core::pbkdf2 from the pinterest-for-woocommerce plugin, often clocking in over 2 seconds.

code.filepath
/home/****/public_html/wp-content/plugins/pinterest-for-woocommerce/vendor/defuse/php-encryption/src/Core.php
code.function
pbkdf2
code.lineno
389
code.namespace
Defuse\Crypto\Core
duration
2052

Is there a known issue, or some way to increase the performance?
