安装硬盘后，我发现 ubuntu 20.04 的启动时间相对较长。在我的 PCI gen4 nvme 上，systemd-analyze
Startup finished in 10.499s (firmware) + 3.259s (loader) + 4.428s (kernel) + 8.384s (userspace) = 26.572s
graphical.target reached after 8.379s in userspace
有时会超过 31 秒！
我的/etc/fstab样子就是这样。
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
# / was on /dev/nvme0n1p2 during installation
UUID=db3bac2a-f735-4b0d-a6b4-dc99fdf1a60b / ext4 errors=remount-ro 0 1
# /boot/efi was on /dev/nvme0n1p1 during installation
UUID=F40C-278D /boot/efi vfat umask=0077 0 1
/swapfile none swap sw 0 0
###/dev/sda1 /work ext4 defaults 0 1
UUID=531b1b74-891f-4f18-a288-cba9990bd31d /work ext4 defaults 0 0
然而由于错误的恢复设备，启动速度慢，内核加载时间长
我尝试编辑 /etc/initramfs-tools/conf.d/resume，但找不到。当我创建文件并遵循其余建议时，没有任何改善。
看到各个论坛上相互矛盾的信息，我完全糊涂了。有人能帮忙吗？
编辑1：随机信息：sudo blkid | grep swap没有给我任何输出！
sudo blkid0输出如下
