My iMac has Poor Performance since High Sierra and I don't know why

Hi,

Ever since my update to High Sierra, my iMac has been sluggish and it has randomly crashed twice or so recently. My internet was a bit...spotty...but I've taken some steps to fix that and it seems to be better...though I'm not sure. Anyhow, my computer is a bit questionable and I'm not sure why. I ran Entrecheck and I'm not seeing any big red flags in the details of the report (though I don't have experience interpreting Entrecheck reports...so maybe there is something I'm missing). All I'm seeing is that report telling me that my Performance is Poor.

Are there any of you all with experience with Entrecheck reports who might be able to interpret this report and tell me if you are seeing anything that might be causing me this trouble?

Thanks in advance!
