SVM hyperparameters using Matlab's fitcsvm and OptimizeHyperparameters

I am building SVM models and will compare their performances, linear vs RBF,
and I'm using OptimizeHyperparameters to get best hyperparameters C (BoxConstraints)
However, when calling OptimizeHyperparameters', 'auto' for the linear model, it takes a long time to get the results, while in RBF model, it takes reasonable time.



 svmmod = fitcsvm(X,Y,'KernelFunction','linear','CacheSize','maximal',...
'OptimizeHyperparameters','auto')


I wonder why, and is there a way to make reduce the runtime?
