开心网-笑话啦 http://www.xiaohua.la This website server is the world's most comprehensive encyclopedia. 2010-9-5 19:42:51 zh-CN http://www.xiaohua.la http://www.xiaohua.la/images/logo_in.jpg 开心网-笑话啦 xiaohua.la vip@xiaohua.la http://www.xiaohua.la/article-1326-1.html http://www.xiaohua.la/article-1326-1.html WEB server, the voice of experience If it is purely a server without dynamic forum for other applications, with P4 support 200-300 people online is no problem, if the WEB system, high efficiency, optimize the script well, can support 300-500 people. Dual XEON line with almost 1,000 limit. If you want traffic, so popular, strong election performance CPU is necessary, justified. Recommended XEON Series entry-level P4, although P4D dual-core performance increase, but the multi-task management, XEON Dual support for multiple customer access and more stable.
     If it is a static page, then, CPU requirements will be lower, static pages do not need to compile the basic card to see if the network bandwidth and, if it is the best picture and more sites have replaced the hard disk SCSI, high speed and high cache SCSI hard drive, for more The small file read more advantage and better stability, and long life.
      However, whether static or dynamic page web site, it is best to use large-capacity memory, particularly now, memory speed is not the important issue, important is two things: one, capacity, 2, ECC ]]> Business Web Hosting 10-07-16 http://www.xiaohua.la/article-1327-1.html http://www.xiaohua.la/article-1327-1.html Apache excellent bandwidth saving Although the shared bandwidth, but the room was the speed limit on each server, now server access than larger, mainly a lot of pictures is relatively bandwidth to conduct some optimization, the basic idea with the hope to give more experienced proposal.

Could think of: defense Daolian, compression and transmission, cache, speed limits.

About Daolian done a lot of restrictions, Daolian basically did not find it, and now mp3, wmv and other media files are they not to visit, and now the server is the real must flow, limited resources, rack their brains to find solutions. (Sorry ah)

Compression, using the mod_deflate, has been accompanied gone. By simple observation, what effect it was good, obvious effect on the html page, but the gif, jpg and other images on to die, because the compression ratio is limited, now the main flow is from the pictures.

Would now like to further optimization: some of the image file cache settings, reduce duplication of downloads, on the other hand would like to be the speed limit for each IP, this should be some relief. But not with too, the Internet search, and were used as mod_expires module, mod_bandwidth module, no child used the two modules do not know how effective, while there are other better options? Hope to have experience to give pointing to the road.
