We have just made this site live about a month or so ago and it just seems to be getting slower and slower. We are somewhat new to wp, but we have wp super cache enabled and we have spoke to our hosting company and all they can say is that it could be too many SQL queries. We've gone through and deleted any plugins we are not using. We've gone through the basic optimization suggestions for wp, but nothing seems to be correcting the issue. Sometimes I'll even get the "error connecting to database" error because it will time out. Any suggestions or help is welcomed. Thanks.
