Online Workgroup Server Performance

Hello, We recently installed the Online Workgroup Server 71.2 TC5 that is bundled with Netscape's LiveWire on a NT 4.0, Dell 4100 server with dual 200MHz Pentium Pro processors, 128MB memory. We are facing two problems: 1. The performance seems to be pretty lethargic, for instance, a select * statement from a 5000 row table takes about 2minutes. Is this the norm? If not, has it got anything to do with the configuration? 2. Very often, we hit against a memory allocation error (406) inspite of all other applications being closed and the virtual memory set at a very high value. Any feedback will be appreciated. This is our first experience with databases, much less Informix and we might be missinng something very ovious to all you gurus. Samatha Rao
