After reading more, I guess that's a dumb question. I'm trying to prevent connections from being rejected. As I understand it, when the server hits the maxThreads limit, then additional connections queue up, until the acceptCount value is finally reached, and then new connections are rejected. Since I am seeing connection refusals, then it is possible that the acceptCount limit is being reached. If so, then it seems there are two ways to address this. I can either increase acceptCount, which gives the server more time to make threads are available, or I can increase maxThreads, in which case more requests can be handled concurrently and the acceptCount may not be reached. Both of these settings improve performance, but in different ways. maxThreads improves performance by allowing more requests to be processed concurrently, while acceptCount improves performance by preventing connections from being refused, which requires requests to be reissued by the client, and that is an expensive process. Which of these approaches is correct? I tend to think increasing maxThreads is better if the server has enough memory and CPU. However, since the impact on memory and CPU depend on the characteristics of the app, that's not a question you can be expected to answer. -Eric Disclaimer : This email and any files transmitted with it are confidential and intended solely for intended recipients.
