This is due to several <tt style="background: #ebebeb; font-size: 13px;">QRegularExpression</tt>s being matched on each line of output.</p>
<p>This diff removes all of the <tt style="background: #ebebeb; font-size: 13px;">QRegularExpression</tt> matchings and uses string comparison instead (e.g. <tt style="background: #ebebeb; font-size: 13px;">startsWith()</tt>, <tt style="background: #ebebeb; font-size: 13px;">contains()</tt> and <tt style="background: #ebebeb; font-size: 13px;">==()</tt>). This necessitated moving the checks from the <tt style="background: #ebebeb; font-size: 13px;">CliProperties</tt> class to the individual <tt style="background: #ebebeb; font-size: 13px;">CliPlugins</tt>, because each plugin has different requirements to which string comparison methods should be used.</p>
<p>Some numbers for my system (6.gen. Core i7 with SSD). Listing linux kernel source archive:<br />
clirar: Before 167 secs, after 7 secs<br />
cli7z: Before 216 secs, after 37 secs<br />
clizip: Before 15 secs, after 5 secs</p>
<p>The difference was less when extracting due to fewer regexp being matched, but still noticable.</p></div></div><br /><div><strong>TEST PLAN</strong><div><p>All unit tests pass.</p>
