Sage 50 Quantum Accounting 2014 - US Edition - Very very slow on a Windows 2003 SBS

Lately, we are experiencing extremely slow performance on the network.   I purged all the data till Dec 31, 2010, reindexed all the chart, jrnl header, jrnl rows and chats.   Did all the tests but performance is still slow.  We have only 5 concurrent users but creating a sales order or invoicing takes anywhere from 1 minute to 'hung' status.  Calling Sage Support is a day's adventure.  Even if I get someone, a purgatory check to see if I have active support and then another long long wait to get a rep.   I am disgusted with support at this moment with the support.   Any suggestions?
