I agree with DocMark, I have seen some slower responses lately. I have been on AC for some time, around 2009 or 2010 but don't think it is related to database. Slowness on imported probably is database size related. There has been some discussion woith AC about prescribing slowness more so with ECPS. Supposedly the next revision of Version 12 which is 12.3 is supposed t help with prescribing issues. I have not changed and am still on V 12.0.0
