My server didn't load at all (check from "vmstat" command). Anybody have idea for tune-up with this requirement. My target is "NCSA" with other server for reduce load. But I think my old server didn't load at all. -_-" =================================================== [root@nagiosnet /root]# vmstat 1 procs -----------memory---------- ---swap-- -----io---- --system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 2 33232 82564 393900 223860 0 0 2 12 8 6 10 7 32 52 0 1 33232 82316 394024 224256 0 0 124 268 1041 170 0 1 40 60 0 2 33232 82068 394164 224376 0 0 140 8 1042 184 0 0 43 57 0 4 33232 81572 394296 224504 0 0 116 804 1045 186 0 0 20 81 0 1 33232 81448 394396 224664 0 0 100 484 1052 174 0 1 20 79 0 1 33232 81200 394544 224516 0 0 148 0 1041 214 1 2 43 54 0 1 33232 80952 394712 224868 0 0 168 0 1052 199 0 0 39 61 0 1 33232 80580 394876 224964 0 0 164 0 1045 189 0 1 40 60 0 1 33232 80208 395020 225080 0 0 144 0 1044 184 0 0 45 54 0 3 33232 79836 395124 225236 0 0 84 1576 1037 190 0 1 16 83 0 1 33232 79712 395196 225424 0 0 72 580 1049 152 0 0 29 71 =================================================== Thank, Gillnaldo SC <hr size=1>Boardwalk for $500?
