title: Python : GridSearchCV is taking too long to execute
body: <p>I am running GridSearchCV on small dataset, which size is (13380,37) and code is as below:</p>
  
  <pre><code>from sklearn.model_selection import RandomizedSearchCV,GridSearchCV
  parameters = {kernel:('linear','rbf','poly'),'C':[1.5,2,3,4,5,6,7,8,9,10],'gamma':[1e-7,1e-6,1e-4,1e-3,1e-2]}
  svc = SVC() 
  clf = GridSearchCV(svc,parameters,n_jobs=38)
  search = clf.fit(X_train,y_train)
  search.best_params_
  </code></pre>
  
  <p>It is running for more than a day. But with the same parameters if i run it on iris dataset,it is giving the result in 1 min. The data is standardized and using multiprocessing too. Am i missing anything here.</p>
