EDIT: performance issues seem to not be due to rendering the vector data[1].
Are you on iOS or Android?
On Android there is the OsmAnd Online GPS Tracker [0].

I can't speak as much to the location searching capability.
I'd be interested in something more FOSSy, myself.
MAPS.ME is gone. We must bring it back: https://telegra.ph/What-happened-to-the-old-MAPSME-12-20

Is OMaps available for phones yet? All I can see is source code.
Very nicely designed. It seems to be gone now however, maybe someone else knows why.

That said I had to piece this together from some commit messages by the F-droid maintainers so I'd prefer a better source myself.
With their map styles [2] OpenAndroMaps are IMO the best hiking maps you can get. They even added very precise elevation data from LIDAR scans recently.

I like its ability to show the different map layers, and it has great information screens that show things like GPS coordinates and such, great for geohashing or geocaching. Also has a cool display of how many satellites are visible and whether they're GPS or GLONASS or whatever.
The track recording feature is also nice, saving as a gpx file that can be easily uploaded to the openstreetmap online iD editor with drag-and-drop.
I've been using OsmAnd and it's okay. The interface is pretty good. It supports offline maps, but not location sharing. Map tiles are kind of slow to load compared to Google Maps, which is odd since the tiles have to be downloaded to local storage. The location search often includes redundant results and whatever database they use to store place data is sparse on details like pictures, hours, or reviews. I'll keep using it to stay de-platformed from Google as much as possible, but I'd be willing to pay a bit for something more responsive and polished.
