why is export VDB extremely slow.......I have around 90MB each frame, but it takes around 2-2.5 minute for simulation to process one frame if export VDB is on....if I remove exporet VDB, it processes it in 30-40 seconds....

90MB is not that high data size to take so much time

Can you try temporarily writing to a different drive? Just to rule out that variable...

I tried a 100mb VDB over here and it took 4.5 seconds to write to a slow external drive.

Maybe you have a rogue firewall or something interrupting the disk access?
