<p>Can't tell much about why it looks slow. You should check about CPU, I/O and some network metrics like bandwidth, ping delays, jitter, lost packets, etc.</p>

<p>With a lot of accounts, I would expect it faster with one instance per account. And this would help if something goes wrong.</p>

<p>Also, I wouldn't use the autorefresh setting and rather start a new fresh instance once the previous is done.</p>
