去大内存垃圾回收性能

Question

I am considering implementing a memory caching daemon in Go. It has potential of getting some serious memory utilization (say, Terabyte). Fragmenting into separate heaps is not a good option, I want it all in one memory space. Does anyone have experience running Go with such huge memory sizes? Is GC going to perform acceptably?

Answer 1

I am trying to do the same but the only projects that gave me a good performance to cache data was the binary tree https://github.com/stathat/treap m which supported more than 1 millons of nodes on memory in one machine Ubuntu 12.0.4 LTS with 8 GB memory. Furthermore, it was fast loading and searching data.

Other projects that I tested was LMDB but not support many nodes on memory, kv, go-cache and goleveldb but no one was as faster to recovery data from memory that treap.
