SaveAsCloudModel is taking more time

[dayanand_rakte]

Below is my source code. 
While debugging I found that below line of code
doc.SaveAsCloudModel(new Guid(hubId), new Guid(projectId), folderId, modelName);

is taking more time and its not stepping to next line .I am able to see the model on ACC but I am not able to get access of Revit Dekstop application as its in freezed state .

I have tested the same code for empty model its working fine. My current model size is 8.33 MB.
Please suggest .
Thanking you in anticipation.

public static async Task<bool> SaveAsCloudWorksharedModel(Document doc, string hubName, string projectName, string folderName , string modelName)
{
string hubId = await GetHubIdByName(hubName);
string projectId = await GetProjectIdByName(hubId, projectName);
string folderId = await GetFolderIdByName(hubId ,projectId, folderName);

hubId = hubId.Substring(2); // skipping prefix b.
projectId = projectId.Substring(2); // skipping prefix b.

try
{

doc.SaveAsCloudModel(new Guid(hubId), new Guid(projectId), folderId, modelName);

if(doc.CanEnableCloudWorksharing())
{
doc.EnableCloudWorksharing();
}
return true;
}
catch (Exception ex)
{
throw;
}

return false;
}

curious, is your intent to create a new model on ACC each time? how often are you running this? are you overwriting or creating it in a different location?
