This may mean that you have excess friction friction along the shift cable. Check for any kinks in the cable housings or dirt in the cable guide under the bottom bracket. How old are the cables and cable housings. It may be time to replace them. Always replace the housings when replacing shift cables.
Also try hosing out the shifters with WD40. This will often restore shifting performance.
I do not believe adjusting the limit screws will help.
