I am also seeing a long delay after entering my password. Long enough
for clients to fail as I am unable to enter my KWallet password within
their timeout period.

I have tries "systemd-analyze", but that only seems to cover the boot process and not login.
The headline from it is: Startup finished in 6.599s (kernel) + 8.008s (userspace) = 14.608s

I sat with a stopwatch and manually timed things.
>From cold-boot (including POST etc) it took 18 seconds to see the login screen.
After enter my password and pressing "Enter" at the login screen, it took 32 seconds to see the desktop. For a vast majority of this time, the progress bar sat at 100% and nothing appeared to be happening.

I've been trying to get get "systemd-bootchart" to show me what happens after login, but I think it only captures the boot process.
Is there any way for me to capture what is causing login to be so slow? I tried to look at https://wiki.ubuntu.com/BootCharting (mentioned in #1353587) but it is missing.
