Optiplex 3050 micro - CPU performance

Hi - first post. Just bought this little micro to use as a media server, and was surprised at how sluggish it is (despite having the 7th Gen 7500T processor and 8GB Ram). I ran some benchmarks and it was very very low scores - CPU-Z was 350.4 for multi threads. Quick shockingly low. Is this is sign of a failing CPU or are they just like this? Is there anything I should be doing to improve this?
