BCH have less trafic then BTC. when more trafic come BCH have problems like BTC...
Bitcoin (Cash) now have x8 BTC's blocksize so will need a x8 the amount of BTC's transactions to have similar problems but before it happens, the blocksize will be upgraded with a hardfork without bifurcation (next May. we have consensus) to 32mb = will be able to process x32 the amount of transactions that BTC can process and fees will be under 0.01$/transaction. Just what bitcoin used to be before Blockstream (aka Block the Stream) started blocking the Blocksize.
but this is no good solution. if more trafic come you hard fork again to 64? 128? hard fork is bad not good to do it every 1-2 year. also x64 block or more big will make blockchain very big and people not can put it in them computer.
