Minecraft Guardian Farm Spawnrate

i am having problems with my guardian farm. We build this huge thing in about a month on our server and now it won't work properly. I hope someone of you got any idea how to fix it.

Setup: We dug out the complete guardian temple, put in layers of water which can be deactivated by dispensers with buckets. At the bottom, everything funnels in a central row, filled with lava where the guardians fall down and die from the fall damage + lava burn. The drops are collected by immense hopper arrays. The complete setup was lit up in about 128 area by me in 4-5 days work. Therefore i get about maximum of 6 monsters spawning in the complete area (which are 99% squids)!

Behaviour: Once i start the farm i get up to 20-30 entity spawns. All guardians. They give some drops and everything is fine. This is all ok for about 1-2 minutes after that the map just stops spawning new guardians. And even then, 20-30 guardians is VERY low compared to what should be possible with this setup.

I added the green-glass minecart track where i afk in in a try to give the whole farm a ton of chunk updates in order to renew spawns. This improved the situation so about 5-10 minutes i get spawns of about 20-30 guardians. After those 5-10 minutes guardians will just stop spawning.

This farm was built on our server and is now played by me in singleplayer, because the server stopped. I use hard difficulty and i should get TONS of drops - nothing happening.

Questions: - What could cause this behaviour? - How can i fix it?

Thanks!

EDIT: I use MC 1.8.3 and i have a pretty bad PC / CPU. Maybe https://bugs.mojang.com/browse/MC-42053 is the reason and there is nothing i can do to fix it?

As for lighting up caves, in a deep ocean biome I found a good way to do it is to get some depth-strider boots, brew some water-breathing potions, and then run along the ocean floor listening for mobs. If you hear mobs, dig down and light up the cave. I was able to get really good spawning at my slime farm using that method.

Where should I AFK for Guardian farm?

If the design is to kill guardians with fall damage or is to have the player AFK near the bottom of the farm, all undersea caves (and any nearby islands) within a 128-block radius will need to be lit, slabbed, or flooded to prevent other hostile mobs from filling the mob cap.

How do you farm guardians in Minecraft?

Before creating a farm, the player may need to conquer an ocean monument, depending on the farm design. To force guardians to spawn within the farm itself, it may be helpful to remove all other water from the spawning zone.

Why are guardians not spawning in my guardian farm?

Guardians spawn inside the 58x58 area of the monument from Y level 39 to 61. They require a 1x2x1 (x,y,z) area to spawn. When there is direct sunlight access to the water source the chance of them spawning is 10 times lower. That's why using a roof drastically improves the rates.
