Optimally Utilising 256MB on Additional Memory on a HP9000 K250
We are currently running DSA7.22 on a HP9000 K250 with 512Mbytes of memory. We will be upgrading this memory to 768Mbytes. (Goodie, Goodie!!!) The machine is a dual processor, and we are running 1 CPU VP and we're running approximately 240 informix sessions. Attached is our onconfig file. What are the best areas to concentrate on in allocating this new memory???

I would double your buffer size, and increase your LRU QUEUES to 125. You can also greatly increase the number of locks you have allocated (don't know if this is a problem for you, depending in number of users and application type). I would also recommend greatly lowiring your LRU_MAX_DIRRTY and LRU_MIN_DIRTY, this will help reduce your checkpoint times (again, depending on application).

Follow my maxim and you'll never go wrong: "No one onconfig change you can ever make will have one-fiftieth of the effect of increasing BUFFERS" I'm sure Obnoxio will back me up to the hilt here! Neil PS of course, you must adjust LRU_MAX/MIN and LRUs in line with your BUFFERS change.
