Plugin for measuring hosting benchmarks stability in time. 
It uses several benchmarks to find out is your hoster stable or not. Like,
<ol>
<li>CPU test</li>
<li>Disk test</li>
<li>Database test</li>
</ol>
The plugin stores benchmarks results and displays detailed graph for every benchmark. The graph shows hosting performance peaks and dips. 
Many peaks and dips mean low hosting stability. You can use this in hosting support conversations.
The plugin uses this <a href="https://github.com/hostingstabilitymeter/php-benchmarks-library" rel="nofollow ugc">benchmarks library</a>. 
Each benchmark takes no more that 1 second. You fully control benchmarks calls frequency.
The plugin may inform you about performance lacks by e-mail. 
Also it may send stability benchmark results to <a href="https://HostingStabilityMeter.Com" rel="nofollow ugc">HostingStabilityMeter.Com</a> if you allow. It helps to maintain a rating of hosters.
Note: <a href="https://HostingStabilityMeter.Com" rel="nofollow ugc">HostingStabilityMeter.Com</a> will never publish or give somebody neither your benchmark results nor hardware information.
