Informix on unixware & memory requirements

Hi I've been using informix online 4.01 and odt 2.0 to support an application that handles more than 30 users simultaneously. Recently we moved to unixware SVR4.2 and informix 5.01.UD1. Since then we have been having problems with memory. It seems that the sqlturbo process has a direct relationship with the size of the shared memory configuration. For example, if the shared memory occupies 7mb, each sqlturbo holds 8mb of ram. :-( Now we are having problems to handle +20 users with 132mb of ram and 60 mb of swap. The shared memory was reduced to 3 mb and now each users (application + sqlturbo) occupies 8mb. Is anybody running informix online 5.01.UD1 on an unixware 1.1 platform ? If so, could you check the size of the shared memory and the size of one sqlturbo ? By the way I've checked the size of the virtual spaces used by a process with ps and the size in the /proc. Please reply to javier@atina.ar since I don't read this list very frequently. If there is enough interest I'll send a summary of the replies.
