Is adding the ‘tbl’ prefix to table names really a problem?

I’m watching some Brent Ozar videos (like this one, for instance ) and he suggests not prefixing tables with ‘tbl’ or ‘TBL’. On the internet I found some blogs saying it adds nothing to documentation, and also that “it takes longer to read it”. **Questions and considerations** - **It this really a problem?** Because I’m prefixing tables with ‘tbl’ since my first dba job (the senior DBA told me to do that for organization). - **Is this something that I need to get rid of?** I made some tests, copying a really big table and giving it the ‘tbl’ prefix, while keeping the other one without it, and I didn’t notice any performance issue.
