Optimizing Network Performance

Some of the diagnostic techniques described in the preceding section, "Testing Network Performance," suggest fixes for problems, such as contacting the operator of a router that's not performing well or fixing a misconfigured /etc/resolv.conf file. This section covers three additional measures you can take to improve performance. Two relate to low-level TCP/IP settings. These values are normally set reasonably, so tweaking them won't help in most cases, but it can help on some networks. The third option, running local servers, can improve performance when you rely on outside servers that you could as easily run closer to home.
