I am having this issue. After a lot of testing with a friend, we have found if he stands 10 chunks from my location and I enable a redstone circuit driving a water dispenser he gets bad FPS drop.
We then disabled the redstone and the FPS returned to normal levels.
Interestingly this could be duplicated using just a bucket with water and no redstone. If he was 10 chunks away and lag free, all I had to do was create a water source with a bucket (no dispenser or anything) and he got bad FPS drop while the water spread. No need for a redstone circuit. This happens anytime he is exactly 10 chunks away regardless of my location (tested as far as x:~2000 z:~2000). At distances less than or further than 10 chunks he got no FPS drop.
