High number of faults, low residual memory and high lock % for mongodb -


first off, here pastebin important numbers (mongostat, db.stats, db.serverstatus).

the machine running on has plenty of memory free:

             total       used       free     shared    buffers     cached mem:         15965       2277      13688          0         89       1630 -/+ buffers/cache:        557      15407 swap:         5119          0       5119

the database files on block device (we had issues due nfs drives) , should working fine. avoid overfilling logs, set --slowms 1000, still lot of queries slow , seems mongodb not interested in using more memory service faster updates.

the use case is 95% updates, queries thrown in when pull out data , compile it. has worked fine setup, trying track down reasons might not working.

i hoping more familiar mongodb can @ numbers , point me in right direction.

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua
