Load Averages: 39.05 75.01 45.33 the apache log is:

Current Time: Sunday, 30-Jan-2011 01:50:13 EST Restart Time: Saturday, 29-Jan-2011 21:51:20 EST Parent Server Generation: 2 Server uptime: 3 hours 58 minutes 53 seconds Total accesses: 149493 - Total Traffic: 2.4 GB CPU Usage: u9.17 s10.66 cu42.82 cs0 - .437% CPU load 10.4 requests/sec - 174.6 kB/second - 16.7 kB/request 121 requests currently being processed, 42 idle workers W_WWW.W_..W.W_W_WCWW..W...W.WWW.WWWW.WW.C_W_.W.WW.WC..W.WW.WW .W.W.W...WWWW...WW.CC.C.._W.WC.WW_WW._W....W.WWW.W.WWW.W..W WW.....WW.W_WWWWW..WCRW..WWCW.WWW__.WWWWCW_W._._WW_W...W...W _W..W..WW.W...._W..._WW.W.WWW.._W.WWW.WWW....WW_.C...W._ Scoreboard Key: "_" Waiting for Connection, "S" Starting up, "R" Reading Request, "W" Sending Reply, "K" Keepalive (read), "D" DNS Lookup, "C" Closing connection, "L" Logging, "G" Gracefully finishing, "I" Idle cleanup of worker, "."
