What's the issue?
One or more tempdb files has slow storage reads or writes. The default value in sp_CheckTempdb is greater than 20 ms. These values are collected from sys.dm_io_virtual_file_stats.
Why is this a problem?
There are any number of reasons why you could have "slow" reads or writes, but basically this comes down to either having less queries using tempdb, or improving the performance of storage.
What should you do about this?
Work with your storage team to make sure that you don't have a failing drive or some other storage issue. Additionally, use your favorite tools or scripts to check index usage to see if any can be dropped or consolidated, or if you can add any that would significantly reduce reads required from queries.

What do the Vulnerability Levels mean?
0 - Information only. This is stuff you should know about your instances like version and service account used, but if you don't know it…well, now you do.
1 - High vulnerability requiring action. These are the issues that could most likely lead to your company being front page news for all the wrong reasons. If your instances have any results at this level then we recommend cancelling that 3-martini lunch and instead huddling with your team to figure out when to address these issues.
2 - High vulnerability to review. These include settings and assigned permissions you should review soon, if not immediately. These findings may not necessarily indicate a clear vulnerability, but we've found unexpected vulnerabilities in these categories at many, many clients.
3 - Potential vulnerability to review. These are configurations or assigned permissions you may be using that could lead to problems for users. Or maybe they're just required for your applications. Either way, we recommend reviewing these to make sure these are correct.
4 – Low vulnerability with recommended action. These are typically security inconsistencies that should be addressed. They aren't likely to cause problems, but you should clean up the mess.
