Embossed text slowing performance dramatically

Hey guys

I've been designing a part which has a lot of embossed text. I have imported the text as a DXF and made it into a block. Positioned it where I want it and cut it into the part. Once this is done the performance of Solidworks goes out the windows... I know theres a lot of faces in the text but its still a pretty simple part?

Any idea?
