Does the iMac possibly have a HDD rather than an SSD (which your custom PC probably has)?
The SSD makes a huge difference in response time. It’s the only reason I’m still using my 5 year old MacBook Pro which has a PCIe SSD and I have no plans to upgrade other than to maybe get TB3 support.
I actually do real development on it, running multiple applications, running Xcode builds, the lot. It does everything I throw at it like a champ.
I’m not sure where you’re getting the 2-3 but that’s definitely not what you should be getting from a modern PC/Mac, especially if they have an SSD.
