Hi,
I have worked on it and find few issues:
– Your Server Seems working Slow
– Image still needs optimization
– After That Use some Paid Plug-in for Cache
Hope your problem is solved.

If you are talk about our theme:
It is well optimized and we used best practice for Writting the theme, You can See how many People are complaining about Speed of Tower in this forum.

Thanks,
