I think , I’m also beginner of klaytn.  
But, experienced from eth networks.

1. Current network transfer to singapore is buffered I guess.  
block time 1secs. so, header information overheads from klay main networks.

2. Contract TX work loads, it makes node works slowly.

3. Change geth (klay) db engine speeds.  
needs to optimize or update to parity clients rocksdb case.

4. Change client main language, go lang is slower than rust or native c/c++.

Conclusion ::

- db engine speed.
- contract VM needs to optimize to increase speed.
- chain main compile language from go to rust or C/c++ (more native languages)
