Long regtest chain synchronization #198
Description
simplexl regtest command takes ~7s to launch. Where ~5s of this is taken up by Electrs indexing the only one tx (after generating 100 initial empty blocks).
This 5s value is not random - it is the frequency of the main loop iterations.
Expected behavior:
The startup process should take 5 seconds or less for the described scenario.
The main loop iteration should be executed after new tx in the mempool, and not any ms before.

Electrs runs an immediate chain/mempool sync run on start, so the 5s loop interval shouldn't cause the slow startup.
One thing you can try it setting
--jsonrpc-import(orJSONRPC_IMPORT=1) to disable indexing from blk files, which is typically much faster for small regtest chains.
