The thing is what are your temperature of the CPU as the CPU can be thermal throttling. In my case, I have a i7-8750H Dell XPS 9570 with 32GB of memory so the specs are not the issue. My system will be fast after a reboot but eventually be almost non-responding and lag after a day or so as the CPU utilization will be close to 100% due to the thermal throttling and that's even modifying the resources with higher limits which does help... This include the following in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\SubSystems\Windows
Windows SharedSection=1024,20480,8192
from Default Value: 1024,20480,768
For GDI handles change the following Registry Keys:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\GDIProcessHandleQuota
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows NT\CurrentVersion\Windows\GDIProcessHandleQuota
Change it to 65536
Range: 256 - 65,536. Default value: 10000
For USER handles change the following Registry Keys:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Windows\USERProcessHandleQuota
HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\Windows NT\CurrentVersion\Windows\USERProcessHandleQuota
Change it to 18000
Range: 200 - 18,000. Default value: 10000
And ofcourse the system will speed up and fast again periodically with the CPU at 30% but the only way to get it fast again is by rebooting because my temps are always in the 90C-100C range most of the time.
Windows 11 has blocked access to the MSR registers so you cannot undervolt directly with either Throtlestop or Intel XTU as undervolting will remedy the problem but with Virtualization enabled, it won't work.

This tells you what undervolting is:
