I’m creating indexes for an Edge class containing about 500 million records
on keys (in, out). The index creation progressed well in the beginning at
about 20,000 items/sec. But then after some time has decreased to <1000
items/sec.

At this speed, it’ll take like 3-4 days!!
Settings used on 16GB RAM and 300GB SSD

Any idea why the speed of indexing decreased so drastically? And how can I
increase the speed of indexing?
