I have developed the workflow contains four path which have four loops in their path. During our development it works fine and able to deploy and test. But when i tried to open the workflow again, it takes more more time, still it doesn't opens up the workflow. it takes 2-3 hours to open the workflow, eventhough it doesn't enables the deploy option.

If any one knows how to resolve this issue, please let me know.

Thanks in advance.
