Not really noticed it tbh:
1.951s snapd.seeded.service
1.673s snapd.service
Seems to be a lot longer than the mounts themselves but even then pretty minimal impact:

Using mistral to calculate this but looks close enough
1921 + 1673 + 242 + 85 + 84 + 84 + 83 + 82 + 81 + 80 + 79 + 77 + 77 + 75 + 74 + 73 + 72 + 71 + 70 + 69 + 68 + 68 + 67 + 66 + 65 + 64 + 63 + 62 + 61 + 60 + 59 + 58 + 57 + 56 + 55 + 54 + 53 + 52 + 52 + 51 + 50 + 48 + 48 + 47 + 46 + 45 + 44 + 43 + 41 + 21 + 18 = 7264ms
So, the total sum of all the time values is 7264 milliseconds, or 7.264 seconds
Removing the snapd services: 7264ms - 3836ms = 3428ms
