It is. But just noticed this. Seems nostr:npub18d4r6wanxkyrdfjdrjqzj2ukua5cas669ew2g5w7lf4a8te7awzqey6lt3 is running electrs so that might be the better choice if mempool space is your primary concern vs a performant wallet or other software you want to connect to your electrum server. There may be other factors to consider too.

I tend to say "dont fix it if it aint broke" but dont heed my own advice
