Selecting blocks is slow
We have a huge performance slowdown in selecting blocks. This is being seen by a user. Here is how to replicate:
- I used the script to create manyMany, and had it create a dataset with 256 files. I bet it shows up with the smaller versions. So, now I have manyMany.e.256.*.
- Master (v5.6.1-1676-gc5bc2677), Linux, remote server (16 processes).
- Open manyMany.e.256.*. Wait for the Apply button to appear. DO NOT HIT THE APPLY BUTTON YET.
- In Blocks, click on the master Block toggle. It's taking 12 seconds to toggle the blocks on and then another 12 seconds to toggle them off!
OK to slip to 5.8 if needed, I am marking as 5.7. This is impacting a customer.
