linux - Does it affect the performance of server if many socket connections are in TIMEWAIT state -


lets have 15000 connections in timewait state affect performance in anyway? problem connecting erlang redis , redis timeout , firing man y queries lets 15000 in 1-2 seconds.

  • problem not socket limit

i open connection fire query , close connection leads many connections in timewait state ok me because have 60k available sockets.

on erlang side have 20 second timewait think more sufficient task redis fast.

what can problem? btw using eredis library

it more efficient not open connection redis @ will, have pool of stable connections. eliminate significant overhead on starting tcp session each time. may face "too many open files" error.

consider tune /etc/sysctl.conf (if on linux). params worth at:

  • net.ipv4.tcp_tw_recycle
  • net.ipv4.tcp_tw_reuse
  • net.ipv4.tcp_fin_timeout

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
