Is there anyway to speed up restarts?

it shouldn't take forever; do you have apps set to reopen when you restart? and how often do you restart? sleeping your mac is perfectly fine (i reboot occasionally... just to clear ram, and get a clean start).
Two steps that I take, which can sometimes help.
Reset NVRAM. (Restart, holding Option-Command-P-R. If you have a Mac with a boot chime, hold the 4 keys until you hear the boot chime twice, then release the keys to let it start up normally. If your Mac does not have a boot chime, hold the keys on boot for 30 seconds, that should be long enough.
The NVRAM reset will clear certain hardware setting, so after a reset, open System Preferences/Startup Disk, and make sure that your boot drive is selected in that pane.
Then, shut down, so your Mac goes off completely. Finally, start up one more time.
I seldom restart my Mac, unless there is a reinstall, or security updates, or other need to restart. It will sometimes be up for a month or so.

After cleaning everything from there, if still slow try reseting the NVRAM. If still slow try booting into Safe Mode (hold down the shift key when you boot until you see the boot progress indicator). Then reboot. This cleans the caches. If still slow check:
/Library/LaunchAgents
/Library/LaunchDaemons
~/Library/LaunchAgents
When my system gets unbearably slow on reboot I move everything from these directories to folders on my desktop and reboot. If the reboot is "normal" I then add them back (usually by reinstalling the program which installed them) one by one until I can isolate the one which is causing the slowness.
My guess is, but can't confirm, that boot Agents/Daemons that go out to the internet cause the delays.
But be very careful, as you can screw up your system if you don't know what you are doing. Virus and network protection launchagents and daemons perform important functions.

right, but did you check? and what sort of HD? default apple SSD? self-installed one? people are offering you help, you need to give us more info (what mac, processor, how old, etc). and have you tried any or all recommendations?
and have you tried the suggestions in this thread? also, is everything else essentially ok? you shouldn't need to restart often (i do occasionally just to 'flush' the ram). just saying, if performance is good, it's a small thing to live with (IF none of the above suggestions help)...
Go to System Report/Information -> Hardware -> SATA Look for a TRIM statement and see if it says NO. So you're not running some 3rd party TRIM package like Disk Sensei? The reason I ask is that it has been one of the most common causes of the slower boot. Disk Sensei's author is in discussion with Apple. Checked the Crucial site and it isn't a matter of not supporting TRIM. They do Garbage Collection (most do) when system is idle, but you can still run TRIM as well (usually and recommended).
You set the drive as the startup disk already? You didn't specifically mention that.
And Crucial SSDs do support TRIM, including on Macs. Which model? How full is it?
Crucial SSD. I bought it right before TRIM support was added.

The one I bought back in 2012 doesn't have TRIM support. It's 500 GB with 275.96 GB free.

Not using a 3rd party Trim Package. I didn't even know it was a thing. So how do I enable it?

Again, which model? Cuz TRIM supported Crucial SSDs even in 2012. Not all OSes did though. Specifically, OS X didn't add it until 10.10 in 2015.
Given that it's half empty, that's good. Drives will slow down dramatically when near full, esp. without TRIM.
And did you actually check the Startup Disk setting? You haven't specifically confirmed that yet.

any antivirus software running? and check System Preferences>Users & Groups>Startup Items; anything there?
1. TRIM is supported with Crucial M4, but you have to enable it manually (like you need to do with any non-Apple SSD).
2. The question we were asking about the Startup Disk is whether or not your Crucial drive has been selected as you default Startup Disk. If it has not, it will still boot off it of course, but your Mac will also spend extra time looking for other startup disks, thus slowing down the restart.
Thanks! I figured it out. I was able to enable TRIM with the trimforce command. Enabling TRIM seems have made reboots super quick. Booting up is not as quick as my Macbook Pro though. Any suggestions?
