I'm not exactly sure what you mean, but if you refer to the normal latency (ie. your main responds about a second quicker then your alts) That's just the server-client lag. It's normal and you will have to live with it, just know that when you press a key that is linked to your alt, he will start instantly, your main just wont see it until a second later.

And others will experience both your chars doing everything at exactly the same time.
