Refer to IT received request to tune up performance of Call Center System (Info-Centrix), Basically IT-infrastructure try to increase ram from 4 GB to 6 GB. However result is the system cannot make use additional RAM (same as aspect) due to Windows is 32Bits(Standard) and MS-SQL 2005 (Standard). So the other way are tune up application or maintain as is until migrate system to new system. I don’t think we shall upgrade hardware.
