Hello On my server (forum) the performance of read and open topics and everything on the forum is super high and less than half second even on pick times. My problem is sql when i have only 10 users per minute the database shows load of cpu: 114% and ram 5%. At pick time it goes to about cpu 170% and ram if i am not wrong is the same about 5%. The problem is at pick time when i try to edit pin unpin move a topic as it takes more than 20 seconds and sometimes i get 500 intrnal server error. (researching about that error i set all folders on correct permissions and i use 775 permissions on the places that need it...) I think something is always hit the sql and don't let it to calm down From cpanel and statistics i was trace the process and got this: Process 27265 attached - interrupt to quit select(4, [3], NULL, NULL, NULL) = 1 (in [3]) fcntl(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0 accept(3, {sa_family=AF_FILE, path=@""}, [8516025424675864578]) = 444 fcntl(3, F_SETFL, O_RDWR) = 0 getsockname(444, {sa_family=AF_FILE, path="/var/lib/mysql\1"...}, [8516025424675864604]) = 0 fcntl(444, F_SETFL, O_RDONLY) = 0 fcntl(444, F_GETFL) = 0x2 (flags O_RDWR) fcntl(444, F_SETFL, O_RDWR|O_NONBLOCK) = 0 setsockopt(444, SOL_IP, IP_TOS, [8], 4) = -1 EOPNOTSUPP (Operation not supported) futex(0xda3544, FUTEX_WAKE_OP_PRIVATE, 1, 1, 0xda3540, {FUTEX_OP_SET, 0, FUTEX_OP_CMP_GT, 1}) = 1 futex(0xda2960, FUTEX_WAKE_PRIVATE, 1) = 1 select(4, [3], NULL, NULL, NULL) = 1 (in [3]) fcntl(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0 accept(3, {sa_family=AF_FILE, path=@""}, [8516025424675864578]) = 70 fcntl(3, F_SETFL, O_RDWR) = 0 getsockname(70, {sa_family=AF_FILE, path="/var/lib/mysql\1"...}, [8516025424675864604]) = 0 fcntl(70, F_SETFL, O_RDONLY) = 0 fcntl(70, F_GETFL) = 0x2 (flags O_RDWR) fcntl(70, F_SETFL, O_RDWR|O_NONBLOCK) = 0 setsockopt(70, SOL_IP, IP_TOS, [8], 4) = -1 EOPNOTSUPP (Operation not supported) futex(0xda3544, FUTEX_WAKE_OP_PRIVATE, 1, 1, 0xda3540, {FUTEX_OP_SET, 0, FUTEX_OP_CMP_GT, 1}) = 1 futex(0xda2960, FUTEX_WAKE_PRIVATE, 1) = 1 select(4, [3], NULL, NULL, NULL) = 1 (in [3]) fcntl(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0 accept(3, {sa_family=AF_FILE, path=@""}, [8516025424675864578]) = 444 fcntl(3, F_SETFL, O_RDWR) = 0 getsockname(444, {sa_family=AF_FILE, path="/var/lib/mysql\1"...}, [8516025424675864604]) = 0 fcntl(444, F_SETFL, O_RDONLY) = 0 fcntl(444, F_GETFL) = 0x2 (flags O_RDWR) fcntl(444, F_SETFL, O_RDWR|O_NONBLOCK) = 0 setsockopt(444, SOL_IP, IP_TOS, [8], 4) = -1 EOPNOTSUPP (Operation not supported) futex(0xda3544, FUTEX_WAKE_OP_PRIVATE, 1, 1, 0xda3540, {FUTEX_OP_SET, 0, FUTEX_OP_CMP_GT, 1}) = 1 futex(0xda2960, FUTEX_WAKE_PRIVATE, 1) = 0 select(4, [3], NULL, NULL, NULL) = 1 (in [3]) fcntl(3, F_SETFL, O_RDWR|O_NONBLOCK) = 0 accept(3, {sa_family=AF_FILE, path=@""}, [8516025424675864578]) = 444 fcntl(3, F_SETFL, O_RDWR) = 0 getsockname(444, {sa_family=AF_FILE, path="/var/lib/mysql\1"...}, [8516025424675864604]) = 0 fcntl(444, F_SETFL, O_RDONLY) = 0 fcntl(444, F_GETFL) = 0x2 (flags O_RDWR) fcntl(444, F_SETFL, O_RDWR|O_NONBLOCK) = 0 Code (markup): If any expert have an idea please let me know My server: 2x Intel Xeon Quad 5405 16GB ram 4x SAS disks raid 10 Thank you
