Significant Input Lag on Arch VM

Howdy,

I'm running an Arch VM on a Windows 11 PC with VMware. I'm experiencing significant and non-regular input lag.

It takes me about 3-4 seconds to type `sudo pacman -Syu` and it takes about 19 seconds for the command to populate in the terminal. Sometimes characters populate at regular speed, or faster, and sometimes they are all super slow.

Environment:

    Arch Linux (no GUI)
    VMware Workstation 20.1.44
    4 vCPUs, 3.9GB RAM
    Open VM Tools installed and vmtoolsd daemon running

Symptoms:

    Commands typed in terminal take seconds to appear.
    Inconsistent lag: most often slow, occasionally it catches up.

Diagnostics Performed:

System Resource Usage:
    CPU and memory usage appear normal (top output attached).

Disk I/O:
    I/O wait times seem normal.
Network Performance:
    Stable network connection.
Kernel Messages:
    No relevant errors in dmesg that I can see
VMware Tools Logs:
    No significant errors in /var/log/vmware-vmsvc.log that pop out.
CPU Features:
    Full virtualization support (lscpu looks good).
Running Services:
    No conflicting services found (systemctl list-units --type=service --state=running output looks good).

Any insights or suggestions to resolve this input lag would be appreciated.

Re: Significant Input Lag on Arch VM

For clarity :
you have followed/read https://wiki.archlinux.org/title/VMware … as_a_guest ?

(top output attached).

no attachments on this forum, you'll have to upload the output somewhere.
see https://wiki.archlinux.org/title/List_o … ted_client

Running Services:
    No conflicting services found (systemctl list-units --type=service --state=running output looks good).

The systemctl list-units commands don't provide all relevant info ,  better use something like

find /etc/systemd -type l -exec test -f {} \; -print | sort

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Re: Significant Input Lag on Arch VM

Ended up just constructing a new install. Don't know what I did.
