add to cart slow - 3.0.6

Hi. I'm in the process of upgrading to 3.0.6 and have installed gzip and smartoptimizer, and am in live mode. Unused addons are uninstalled and statistics are off, but the add to cart funtion about 3 loading cycles as opposed to my 2.1.4 store that adds almost immediately. I thought it might be the table of options addon but disabled that and there is still no difference. It is extremely frustrating. Just about everything is slow! (both are on the same server)

Any suggestions?

current 2.1.4: site: www _ thebutterfygrove _ com

new 3.0.6 site: 214 _ thebutterflygrove _ com

Thank you…
