TERRIBLE performance, 2011 on High Sierra

[TSE]

I have a 2011 MBP, 15" with 16 GBs of RAM, a 500GB SSD, and the 1GB 6750m HD.

My performance on the computer has been absolutely GOD awful since upgrading to High Sierra. I'm talking 5 - 10 bounces when trying to open up Chrome, laggy even when just typing at times, and web page loading is just bad too. This has been the worst operating system experience I have ever had, including Vista.

I thought maybe it was because I upgraded it from El Capitan, so I did a fresh install of High Sierra and same thing.

Very frustrated at this laptop and really don't want to get a new $2500 MacBook Pro that has similar CPU performance, the same amount of RAM, and the same hard drive space.

The 2017 15" MBPs are actually quite a bit faster than your machine in every way - CPU, GPU, SDD and RAM speed. But back to your problem - that's actually quite strange, High Sierra runs perfectly fine on my 2012 quad-core Mac Mini, which should be relatively similar performance-wise to your MBP. What does activity monitor show?

It should run fine. I'd start with your SATA cable

Just upgraded El Capitan to High Sierra on a 2011 Macbook Pro 13 w/ 4gig RAM and it runs fantastic.

Thank you for sharing this info.

I'm using a late 2011 (A1278) MBP, with 16 Gb RAM, SSD.

I am still using Yosemite OS X, and often wonder if there is any real benefit to upgrading to High Sierra.
