TIDTCPCMDServer multi broadcast lists

Using Indy 10

Looking for a faster way to support multiple broadcast lists for multiple chats on same TcpCmdServer component

For example, if client #1 is in 3 chats, it will be in 3 lists, etc..

at this time, i'm using a very time consuming loop to search for a match of the peerIP within a specific string.

  ContextsList := svr.Contexts.LockList;
  with ContextsList do
    for i := 0 to svr.Contexts.Count-1  do
      cx := ContextsList[i];
      if pos(cx.peerIp, sBroadcastList)>0 then

as it stands, the current implementation is the fastest.
thanks for the effort.  partial points awarded

Maybe you can use TList where you can store unique client id (maybe if you transfer ip address from string
to integer v1.v2.v3.v4 --> v1*16777216+v2*65536+v3*256+v4) - searching integer is faster than string.
controlrAuthor Commented:
that will be actually slower, as the user ID is already sorted and IP's are a secondary field..

Would TIDTCPCMDServer  be able to handle a paralleled  loop workload on  the connections?  or will it cause issues?

partial points for efforts, solution is not faster than current implementation
