Bcash solves nothing. The average block time is still 10 minutes. Your transaction is more likely to get in to the next block with Bcash because each block is barely 10-20% full because no one uses it. However, since their hash rate is so low and so centralized, 1 Bcash confirmation is not even close to as secure as 1 BTC confirmation, and so you have to wait hours longer to achieve the same level of security. https://howmanyconfs.com puts the current figure at over 4 days to achieve what bitcoin achieves in an hour. Kraken want 4 confirmations for bitcoin deposits, but 15 for Bcash. Coinbase want 3 for bitcoin and 12 for Bcash. Gemini want 3 for bitcoin and 15 for Bcash. As you can see, Bcash takes significantly longer than bitcoin by all metrics.
