Hi,
<div class="">Give a look to this article:</div>
<div class=""><a href="https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/t2-credits-baseline-concepts.html" class="">https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/t2-credits-baseline-concepts.html</a></div>
<div class=""><br class="">
</div>
<div class="">It’s possible that you have one of these VMs, that on average deliver only a low (even only down to 5%) performance than the actual CPU performance (it might seem fast at the first run, if you didn’t run anything, but the algorithm of CPU credits
 will make runs be slow, eventually).</div>
<div class=""><br class="">
</div>
<div class="">Also, crashes might be due to limited RAM.</div>
<div class=""><br class="">
</div>
<div class="">HTH,</div>

<div class="">Dear QE users and devalopers</div>
<div class="">I'm running QE on Amazon Web Services (AWS) and I see that the run times are very bad compared to other systems that I use and I also encountered crashes which I cannot understand the reason for them. Does anyone work on AWS and know something
 about the performance and special compilation issues?</div>
<div class="">Thank you</div>
