### JAVA Code
```
channel =
ManagedChannelBuilder.forTarget(param.getTarget()).build();
long channelStart = System.currentTimeMillis();
asyncStub = ASRRouteGrpc.newStub(channel);
asrResponseStreamObserver = new
ASRResponseStreamObserver(speechTranscriberListener);
requestObserver = asyncStub.route(asrResponseStreamObserver);
RouteRequest requestConf = newRequestHead(param);
traceId = requestConf.getAsrConfig().getTraceId();
ConnectivityState currentChannelState = channel.getState(true);
while (currentChannelState != ConnectivityState.READY) {
CountDownLatch latchUntilChannelReady = new
CountDownLatch(1);
channel.notifyWhenStateChanged(currentChannelState,
latchUntilChannelReady::countDown);
latchUntilChannelReady.await();
currentChannelState = channel.getState(true);
if (currentChannelState == ConnectivityState.CONNECTING) {
long channelConnecting = System.currentTimeMillis();
LOGGER.info("The transition from idle state to
connecting takes: {} ms", channelConnecting - channelStart);
}
}
long channelReady = System.currentTimeMillis();
if (LOGGER.isInfoEnabled()) {
LOGGER.info("Trace id: {}, channel start time: {}, channel
ready time: {}, creating channel takes: {} ms", traceId, channelStart,
channelReady,
channelReady - channelStart);
}
```
### LOGGER
```
2023-08-22 14:12:34,816 INFO client.ASRClient - The transition from idle
state to connecting takes: 1009 ms
2023-08-22 14:12:34,841 INFO client.ASRClient - Trace id:
6afd2c67-e8c5-4cea-bd5c-4b82591a52aa, channel start time: 1692684753807,
channel ready time: 1692684754841, creating channel takes: 1034 ms
```
### Description
#### code logic
1. first create channel
2. mark a time stamp(channelStart) after the channel is created
3. get the state of channel ,the state is IDEL
4. when the state of channel changes from IDEL to CONNECTING,mark a time
stamp(channelConnecting)
5. when the state of channel changes from CONNECTING to READY, mark a time
stamp(channelReady)
#### Log info
1. It takes 1009ms for channel from IDLE state to CONNECTING state.
2. It takes 25ms for channel from CONNECTIONG state to READY state.
### What's i supposed
1. Does it take too long for a channel to change from IDLE to CONNECTING?
2. I want to reduce the time it takes for a channel to go from IDLE to
CONNECTING.
