<div class="markdown_content"><p>Hello everyone,</p> <p>In the <a class="" href="https://help.codesys.com/webapp/ac_pm_overview;product=core_Application_Composer;version=3.5.16.0" rel="nofollow">documentation</a> for the Persistent Manager module, it says that <em>"the writing of a big amount of persistent variables may take a lot of time and can block the respective task very long"</em>.</p> <p>How much is "a big amount" ? For example if it's running on a raspberry Pi 3 with 1GB of RAM and a writing speed of around 15 MB/s ?</p> <p>Also there is an indication of a size limitation in the documentation, but what is the limitation on the updating speed ? <br/> For example if I want to store one REAL variable periodically, how fast can I go ? Every 3ms ? 10 ms ? 500ms ?</p> <p>Thank you for your support,<br/> BR</p></div>
