Advice on slow reads

[kljensen]

Hi friends, I'd be grateful for some advice. I have a database created with rocksdict of about 1tb in size. My random reads of 1k keys takes about 20s without a warm cache. And, when reading those keys I see only a single active cpu core, which surprises me. Can you offer me some advice for speeding up my reads. Thanks!

How is the random read speed of the database when it is smaller? And what about the disk performance? Is it HDD or SSD?

I will test this. Thanks @Congyuwang. Before I do do, can I ask you about multi threading? How can that be enabled?
