Re: Good Buffer Size For Tuning Informix?
Hi Michael, The only really important factor in determining the number of buffers is the read and write cache hit ratios reported by tbstat -p. Keep increasing the number of buffers until these cache hit rates do not increase when the system is running a 'normal' workload. This …
Good Buffer Size For Tuning Informix?
Michael, Tuning is a site issue but I believe that 30% of RAM is the recommended max. After tuning everything else to get your engine performance as good as possible try adjusting the number of buffers to bring your shared memory usage up to this 30% figure. Really at the end o…
