In the configuration, I generally put the resource consumption of a large site independent of a pool, general BBS or generated HTML system about 5 stations a pool. Common sites and some enterprise sites share a pool.2, according to the experience of WLMMC, in the case of the server hardware, generally do not limit the use of site memory, so that the site can be guaranteed to run, will not appear the user off the li
