The eCommerce site I performance test runs BroadVision on Solaris 2.7 on Sun OS 5.7. The log files produced by BroadVision (and other log files) take up system memory and eventually consume all available memory. When I delete the files the memory is released. I was told Solaris puts frequently accessed files in memory to eliminate IO latency. Is this a configuration that can be changed? Is it a bad idea to change it? I would like to run a test to find out. Does anyone have any more information or thoughts on this characteristic of Solaris?
