Hello~~
I'm very sorry for the late reply.
We have found the reason of this issue is our buggy-code which hooks "SetWindowsHookEx" API.
After hooking the API, our buggy-code makes the other hooking-operations slow down.
Thank you for your support.

Thanks for letting us know, and I'm happy to hear that madCodeHook was not at fault!
