Hostile Mobs do not See the Player Immediately

(UNRELATED to my other ticket about witches, MC-48374.)

Nearly every hostile mob I've seen (since the 14w06a snapshot) did not notice me at all, even when I'm standing idle within their aggro distance, for about a minimum of half a second, to a maximum of about six.

To Reproduce

1.) Look for or spawn any mob that is initially hostile, besides all mobs I listed below.
2.) If you are in creative, switch to survival.
3.) The mob will take slightly longer to notice you then it would, with slight time variations each time.

The following mobs do not experience this issue:
-All neutral mobs (Enderman, zombie pigman, wolf, spider and cave spider (daytime), wither boss itself)
-Wither boss side heads
-Ender dragon
-Slimes
-Magma cubes
-Ghasts (They can't see you until you get almost eye level with them, but when you do they immediately shoot, I made another ticket about this)

The following do experience this issue:
-All other initially hostile mobs (Zombie, creeper, blaze, guardian, silverfish, shulker, etc.)

NOTE I would like to note that it appears to affect mob-to-mob interactions as well. Tested with iron golems, snow golems, and mobs that now attack iron golems. That is, all of them have a short time before noticing each other. Happens with zombies vs. villagers and guardians vs. squids. They react as they would with the player.

Confirmed for spiders

I've noticed it with all mobs.

Itouch2

Yes

I can confirm it too and this bug still appears.

Paul Smith, you had an issue about the ghast.

Sonicwave

Doesn't seem to happen with Zombies and Villagers (but then again Zombies can detect Villagers through blocks).

Can some Mojang employee please tell the public why this is considered working as intended? Everyone would like to know.

I'm not Mojang but I'm guessing it's because mobs do not have god-like reflexes and/or eyes on their back.

Maybe their brains are just not smart enough. After all, they actually attack you for absolutely no reason, and creepers commit suicide on purpose.

and also wouldn't it be fun to run up to a mob and backstab it, I do it frequently while mob fighting. this is a feature.

The greatest reason for this bug would be that first of all, ever since 1.8, although it was said that the game has been made a lot lag-free, there is still lag in the client. This mob lag actually doesn't happen on a fast computer or on servers. It does happen on servers but if the server is fast, then there is no problem. The biggest reason for this lag I guess would be because of the higher number of entities. If there are armor stands, command blocks, redstones, mobs, etc. then this can be seen clearly. Sometimes in survival, the mobs stop moving but we can move and do anything. BUT NOTICE: When we attack them, they won't get attacked. And also, if we wait for the game to work, all of a sudden, the game goes too fast and then the mobs attack us 5-7 times in 1 sec. Also I guess if we check the logs, sometimes it says the message like: "Can't keep up! Did the system time change, or is the server overloaded? Running "x"ms behind, skipping "y" tick(s)".
The running of "x" minisecs behind forces to skip some ticks, which causes the mobs to attack all of a sudden. This only happens in SinglePlayer, or MultiPlayer if the server is overloaded or can't keep up. But if this happens in MultiPlayer, it won't show in our logs. Rather it shows in the admins log. (Well, because HIS server is lagging lelz)
