Google Drive API response is very slow -


we using google drive v3 api manage documents in our web application. have simple use case in user clicks on button , backend needs copy 5-10 files source destination folder. have tested 6 files in source folder , api took 7 seconds. have used batching invoke copy file api. following code same:

adding requests queue:

for(template template: templates) {     file file = new file();     file.setparents(collections.singletonlist(parentfileid));     file.setname(template.getname());     file.setwriterscanshare(false);     file.setviewerscancopycontent(false);      map<string, string> appproperties = new hashmap<>();     appproperties.put(template_code_prop_name, template.getcode());     file.setappproperties(appproperties);      driveservice.files().copy(template.getfileid(), file)          .setfields("id, name, appproperties, webviewlink, iconlink, mimetype")          .queue(batch, callback); }

handle response after batch executed successfully:

jsonbatchcallback<file> callback = new jsonbatchcallback<file>() {      @override     public void onsuccess(file file, httpheaders responseheaders) throws ioexception {         log.info("copied file - " + file.getname() + "   " + file.getid());     }      @override     public void onfailure(googlejsonerror e, httpheaders responseheaders) throws ioexception {         log.severe("failed copy file " + e.getcode() + "   " + e.getmessage());         throw new exception();     }            };

i have followed best practices recommended google:

  1. set fields required in response partial response instead of complete response
  2. use batching invoking api

the api taking 7 seconds complete simple task. bad performance user experience perspective. i know if expected delay or doing wrong here ?
