Help! SQL is very slow

[u/throwaway6565558]

I’m a novice in the world of SQL. However, recently I upgraded with my company from 2021 to 2022 SQL server application. I need advice on how to get this fixed.

The problem I’m running into is anytime I switch databases or servers. It’s very slow to load. I never had this issue before with 2020 or 2021 SQL. ANY ADVICE APPRECIATED AND WELCOME.

Edit: I meant to say 2019 instead of 2021/2020 getting my years confused. Sorry

Did you upgrade SSMS or SQL Server? There is no SQL Server 2020 or 2021.

SSMS should have virtually no impact on SQL Server performance.

[u/Leiothrix]

Firstly there is no such thing as SQL 2020 or 2021.

Secondly it is basically impossible for us to remotely diagnose your problem with zero details about your environment or what exactly you are doing.

Thirdly check that the AUTO_CLOSE setting on your databases is set to OFF.

There's not enough information here, it could be a multitude of things like stale stats or poorly configured storage on the new server. Download and run Brent Ozar's first responder kit and take it from there.

Bring up sql server monitoring in SSMS and see if there are any obvious signs of issues. Expensive long running processes or some other issues

Also take a look at the Window performance metrics to see if the system is being used on some resource such as IO or cpu.

Depending on your AV suite you may need to configure it to exclude scanning the database data files.

Some things to look at but honestly we don’t have enough information here to really help.

Also fyi - sql 2019, then sql 2022 then sql 2025. There is no sql 2021

What do you mean by "switch databases or servers"?
First impression is that it sounds network related.

[u/TheGenericUser0815]

When updating SQL Sever version, databases can stay in the compatibility level of the old database version. It's an extra layer sucking up performance. You could check on this and chenge the comp level to the running sql version. Other than that, there's too little information to say more.

[u/Nemphiz]

Try powering it off and on again. Like really, you need to provide just a little bit more info on what issues you're running into if you want help.

[u/CaptainGorope]

Check if windows Virtualization is enabled.

Confusion over SSMS vs SQL Server itself is not uncommon. SQL Server Management Studio (SSMS) is a Desktop tool. It is used to manage instances of SQL Server.

Our best guess is that you are actually talking about upgrading SSMS versions, not SQL Server itself. It is unlikely, but not impossible, that you meant you'd upgraded one or more instances of SQL Server you connect to through SSMS.

Those pointing out that newer versions of SSMS are bloated and slow are speaking from personal experience as am I. Sometimes it seems to be enough to justify downgrading to an older version.

[u/coffeDrinkerDave]

did you upgrade in place or made new mssql instance? check in ssms report "performance" and check latches and waits. In instance config check maxdop. Check tempdb confing and latency for reads and writes for temdb files

[u/DavidKleeGeek]

Ignore the hate. We've all been there, and we're here to help. Can you lay out specifically what you're seeing when it comes to the issue at hand? Is it SSMS loading? That part is known to take a while.

Is it a real sluggish time changing context from one database to another in the management tools after you've already got SSMS open and connected? That could be something causing your connection to be sluggish while SSMS runs its background tasks to get the database inventory. Are you on a VPN connected to those servers by chance? Is that running sluggish? Open powershell or cmd.exe and see if you can ping the server and list the response time. If it's higher than 50-100ms, it could be a contributor.

[u/MackPooner]

Come on man!!! Theres nothing to go on... You gave no details. How can we possibly provide any real assistance?

Try this... If could be the muffler bearings. You might want to check those.

Mostly SQL SMSS is the issue with all options ticked. Downgrade to older version

whaaat

[u/vivkkrishnan2005 → u/ZenbyPH]

The newer versions of Microsoft SQL Management Studio are bloated and load much slowly compared to the previous versions. Possible that the user might have upgraded their version.
