Troubleshooting Tips - Long Unix Scan Times

I am scanning a single Linux host using Authentication, and it takes more than 80 minutes to complete. I am after some advice on how to reduce this time so that I can scan my whole fleet in a reasonable time frame.

My option profile originally included full TCP and UDP scans. I reduced the UDP ports down to 30, since I was seeing QID45050 (UDP Scanning Limited to Default Ports). This made no difference to scan duration.

Any tips on where to look next?
