Illustrator has always been sluggish on startup, but 27 seconds on a recent SSD MBP is totally unacceptable IMO.
By comparison PS is ready to go in 7sec.
Standard install CC 2018 / Il 22 on MacOS 10.13.1
Our typical launch numbers on a SSD MBP is around 6-7 seconds hence we would like to understand more about the issue and problem.
Please get in touch with us at firstname.lastname@example.org or any of the other support channels – https://helpx.adobe.com/support.html . Since this is not a generic issue that we can reproduce at our end, we will need someone to look into your machine to figure out what is going on here.

Hi Ashutosh, Thanks for coming back, I have only just been notified of this. I'm doing pre-release work with Ps and Lr and see no performance issues (making allowances for a laptop). On the other hand Il has always been a very slow-launching app for me. The machine is currently running a lot of apps and it takes 40 sec for the Illustrator banner to appear.
I always maintain 20-50% of the SSD as free space
