<li>Update rvm on DSpace Test and CGSpace as there was a <a href="https://github.com/justinsteven/advisories/blob/master/2017_rvm_cd_command_execution.md">security disclosure about versions <= 1.28.0</a></li>

&lt;li&gt;Update rvm on DSpace Test and CGSpace as there was a &lt;a href=&#34;https://github.com/justinsteven/advisories/blob/master/2017_rvm_cd_command_execution.md&#34;&gt;security disclosure about versions less than 1.28.0&lt;/a&gt;&lt;/li&gt;

&lt;li&gt;Looking at memory info from munin on CGSpace:&lt;/li&gt;
&lt;/ul&gt;

&lt;ul&gt;
&lt;li&gt;We are using only ~8GB of RAM for applications, and 16GB for caches!&lt;/li&gt;
&lt;li&gt;The Linode machine we&amp;rsquo;re on has 24GB of RAM but only because that&amp;rsquo;s the only instance that had enough disk space for us (384GB)&amp;hellip;&lt;/li&gt;
&lt;li&gt;We should probably look into Google Compute Engine or Digital Ocean where we can get more storage without having to follow a linear increase in instance pricing for CPU/memory as well&lt;/li&gt;
&lt;li&gt;Especially because we only use 2 out of 8 CPUs basically:&lt;/li&gt;
&lt;/ul&gt;
