Just make a timer for each player, and that's it:

pawn Код:

new uSpeed[MAX_PLAYERS];
forward Speed(playerid);
public OnPlayerConnect(playerid)
{
    uSpeed[playerid]=SetTimerEx("Speed",1000,true,"i",playerid);
    return 1;
}

public OnPlayerDisconnect(playerid, reason)
{
    KillTimer(uSpeed[playerid]);
    return 1;
}

public Speed(playerid)
{
    new string[128];
    format(string,128,"Jusu greitis\n%d",GetPlayerSpeed(playerid));
    SetObjectMaterialText(objektas,stri, 0, OBJECT_MATERIAL_SIZE_256x128,\"Arial", 55, 0, 0xB8860BAA, 0xFF000000, OBJECT_MATERIAL_TEXT_ALIGN_CENTER);
    return 1;
}
