服务器负载很高,是配置太低了么？
一台服务器专门用作图片存放,最近放了些flv视频文件上去,负载马上就上去了,想请教一下各位大大是不是配置太低了
tasks 在500+的时候,负载在10+ 在600~700的时候,负载会彪到100+ ------------------------------------------------------------------------------------------------------------- 主机配置 AMD Sempron(tm) Processor 3100+ 1G内存 ------------------------------------------------------------------------------------------------------------- /usr/local/apache/bin/apachectl status Apache Server Status for localhost Server Version: Apache/2.2.9 (Unix) mod_ssl/2.2.9 OpenSSL/0.9.8b mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 PHP/5.2.5 Server Built: Jun 27 2008 17:44:29 _________________________________________________________________ Current Time: Sunday, 29-Jun-2008 07:50:09 EDT Restart Time: Saturday, 28-Jun-2008 11:59:14 EDT Parent Server Generation: 1 Server uptime: 19 hours 50 minutes 55 seconds Total accesses: 4220740 - Total Traffic: 990.5 GB CPU Usage: u21.15 s47.86 cu0 cs0 - .0966% CPU load 59.1 requests/sec - 14.2 MB/second - 246.1 kB/request 251 requests currently being processed, 44 idle workers .KK.CKWWKK.CWKWWW_.KK_KWWWKKK__W.KW.WWW._K.KWCWWKKK.K.KKK..K.W_K WKW.W.K_W_WWKK.KKWKKWKWKWWK_WWWCCK_KKKKKCKW.W.WK_CCWCKKWKKWWW_KK K_CWK.KWK_K___WC_KWCKKKWKK._WWWWWC..WWKKW_WW_WKKK_WKWKKWW_WKK..W KKWKKWW_W.KWWW.KKW.KW_WKW.W_W.CWKW.K_.K.W.K.KKK.W.C...K..K_.....
