We're running SQL 2012 which host(s two database Sage300 and POS both database is used by approximately 40 concurrent users daily.
We have notice that when ever we try to perform a post from either software if this query is long our entire operation immediately experiences performance issues and at time "not responding". once this process (SQL query) is stopped then all is well again.
Server Specs:
64GB Memory
120 SSD HDD
2x Intel Xeon E5-2600 v4 processors
What would you suggest ?
