Large Array Read and Write Speed

[ramezanifar]

For an array of length 100, it takes approximately 3 ms to read/write. Proportionally, for an array of length 1000 it takes 30 ms which is way to long for my use case. I was hoping reading an array of 1000 is not 10 times slower than reading an array of 100. One transaction should be normally faster because of less overhead. Can you please advice?
