Work units used to take around 1 hour 30 minutes to complete but recently its taking one unit around 4 hours to complete. Is this normal or is something happening to my computer?

It's normal... They are somewhat variable. I've had some complete in about an hour and a half and some go as long as 10 hours. Also, these work units suffer if you run too many together due to memory requirements and the overloading of cache.

The longer the amino acids sequence of the protein being studied, the longer the runtime. What's happening to you is completely normal. :)

Doneske or anybody else who might know -
with the standard ratio between Cancer/AIDS2/MIP (the three active projects that don't suffer a windows penalty), should people with high core counts like Threadripper get any penalty for simultaneous throughput? |

I have used 8-core Intel chips and a 16-core Ryzen 1700: (1) I have seen no penalty for Cancer at all (2) There is some penalty for MIP. I limit it to two work units running at a time. (3) Don't know about AIDS2, but I doubt it. It is a bit unusual to see one. |

I thought it was referred to as 8 real cores and 8 virtual cores to give you a total of 16 cores. I am not splitting hairs either  |

MIP is not written to use the same core for 2 jobs (when in HT mode)...so I'd suggest run those 1-2 jobs per CPU. All others, no limits. |

I am not splitting hairs either No, each real core is allowed to execute instructions from either of two threads, depending on the availability of the hardware resources. That way, you keep the hardware of the real core busy more of the time, allowing an increase in output. To the OS, each "virtual" core looks like a real core, so it sees 16 cores.
