Hi NEOJG,
When the application is run, the protected files get decrypted at the runtime. This causes some difference in performance. The delay can vary depending on the size of protected file or number of methods protected in case of .Net.
Please ensure that only the important methods that have your intellectual property code, are protected. Protecting methods that do not contain important code (that needs to be secured) will cause unnecessary decryption time.
Try the following-
1. Open the envelope and add your exe/dll (do not use any saved envelope project file)
2. There should be some methods selected by default. Protect the files without any change in the methods list
3. Check the performance difference
4. In second test, add the file in envelope and click "Clear All" to de-select all methods
5. Now select only your important methods and protect the files
6. Check for the difference in performance
Do not use "Select All" options
Please perform these tests and share the results.
Also confirm the version of envelope used for protection.
Regards,
Ashish
