Monterey extremely slow

Questioner General

Since upgrading to Monterey, any internet operation is slow - painfully slow. Can take several minutes to load a page in Safari or update the Notes through iCloud. I have tried all the the advice e.g. resetting SMC. NVRAM, emptying cache, etc apart from downgrading to Big Sur as this seems a drastic step.

Thanks for your help. I installed Monterey over a month ago and since was painfully slow. iMac was installed with a mechanical drive which was quite slow. Upgrading to Monterey from Big Sur slowed it down even further. I upgraded the mechanical drive to an SSD which improved performance for anything except network operations.



I enabled TRIM on the SSD - which seems to have helped alongside removing CleanMyMac.



These two actions have seemed to restore performance.

Is the issue Only Speed of internet ?



Point # 2 - Are there any AntiVirus, Disk Cleaner, Optimizers, Un-installers, etc installed which should be removed as per Developers Instructions. They are useless, unneeded, cause havoc and interfere with the normal operation of the OS and may even Corrupt the OS requiring a Reinstallation.



The The Built in Security  is all that is required.



Point # 2 A - Commercial VPNs should only be used if Mandated by Corporate Head Office for working remotely. Otherwise - ones Privacy and Security touted by the VPN is suspect.

Clean my Mac has been known to cause problem. Such apps are not needed too. I would uninstall them using the developer's instructions.

You just installed Monterey yesterday and after an upgrade the new OS has to disk indexing and other things which slow the computer. I can see this since MDworker is taking CPU and that is the Spotlight search indexing.

Is Disk0/1 you startup disk? It is internal?

disk0 - CT1000BX500SSD1 1.00 TB (Solid State - TRIM: No)

Internal SATA 6 Gigabit Serial ATA

disk0s1 134 MB

disk0s2 - EFI (MS-DOS FAT32) [EFI] 210 MB

disk0s3 [APFS Container] 980.00 GB

disk1 [APFS Virtual drive] 980.00 GB (Shared by 6 volumes)

disk1s1 (APFS) [Core Storage Container] (Shared - 15.69 GB used)

disk1s1s1 - Macintosh HD (APFS) (Shared - 15.69 GB used)

disk1s2 - Preboot (APFS) [APFS Preboot] (Shared - 312 MB used)

disk1s3 - Recovery (APFS) [Recovery] (Shared - 1.10 GB used)

disk1s4 - VM (APFS) [APFS VM] (Shared - 9.66 GB used)

disk1s5 - Macintosh HD - Data (APFS) [APFS Virtual drive] (Shared - 313.79 GB used)

disk1s6 - Update (APFS) (Shared - 2 MB used)



  1. I note that TRIM is not enabled and that can slow disk operations. Etrecheck notes:

SSD too slow - SSD is showing poor performance.



Did you replace the original disk?



What is this disk:

disk7s1 - Macintosh HD

980.00 GB (Shared - 15.69 GB used, 729.79 GB free)

APFS

Mount point: /Volumes/M************1

Owners enabled: No

Read-only: Yes



disk7s5 - Macintosh HD - Data

980.00 GB (Shared - 224.31 GB used, 729.81 GB available, 729.79 GB free)

APFS

Mount point: /Volumes/Macintosh HD - Data

Owners enabled: No



I ask since a disk titled Macintosh HD is usually the startup disk.

Thank you - I removed CleanMyMac and alongside enabling TRIM, it seems to have restored performance.
