Performance blocks requested!

So as far as performance goes, Id like to see the following:

Depleted uranium gyroscopes. Basically these weigh 150 tons, and they are there for capital ships to not have to spend so much pcu on gyros.

Plasma Airlocks. These cost power to maintain, and they do nothing to stop bullets or shells going through. However, they stop air from going through. There are blocks right now in the game that are weirdly shaped and allow 1 pcu airlocks. However, this really needs to be a feature, and not a bug, because this improves server performance. Adding a power maintenace could make them cost 5 pcu? But still do the same job as the ugly 1 pcu block. Compare to the 200ish PCU normal airlocks take.

complex blocks. Basically these are blocks that have multiple things going on. Unavailable for players, and only npcs get them. When they are hit, the whole block gets destroyed instead of fragmenting, and since the whole block is a part of a ship instead of many small pieces of the ship, the npc ships cost nothing for the server to maintain. If an npc ship has 5 blocks instead of 50+ blocks, the performance cost will be lower.

Advanced gravity generators. Basically stronger variants of existing gravity drive generators, but with a change: advanced gravity generators do not have their effects stack. Reason being that if you want high gravity fields, you currently stack gravity gens, leading to pcu glut on gravity gens. Without stacking, people only want to build 1 advanced gravity generator instead of say... 10 and then they configure the acceleration they want. Why? Lower total pcu expended this way.

5d small thrusters. These are ion and atmospheric and hydro variants. Basically its a block shaped as if 5 hydro thrusters were put on a conveyor junction. Why? These would fire only in the direction that the player's keys were pressing. Instead of using 75 pcu in thrusters and 10 pcu in a conveyor junction, this new block costs 25 pcu. Its perfect for small drones or small ships that need thrusters, and it makes building said ships more economically viable.

Long junctions. These are blocks that basically look like 6 conveyor junctions stacked on top of one another. Except its one block with same pcu cost as a normal conveyor junction.

medium junctions. These blocks also look like stacked junctions. 3 blocks long. Same cost as normal junction.

9 grid junctions. Basically these look like a 3x3 grid of conveyor junctions but its 1 block.

Make the large thrusters more thrust efficient or equal thrust efficient in space to thrust ratios compared to a 3x3 grid of small thrusters. Why? People should use large thrusters whenever possible on large grid ships, and if they are using small thrusters for smaller mining ships that are large grid it is what it is. But thrust is an important factor and people are building fighters that don't use large grid thrusters because its better in a dogfight to use small thrusters. Those fighters eat pcu and lead to lower total numbers of stuff people can use.
