SSMS very laggy when typing a query

  • This is a strange one. I am typing a query in SQL Server Management Studio. Nothing is executing on the server. I actually get an hourglass as I type the query at which point I am forced to wait up to 10 seconds before I can type again. I may get one word typed before I get another hourglass.

    I tried to RDP to the server directly (thinking it may be something on my computer) and the problem happened there as well. I did a task manager and all the processors were maxed out and the memory usage was maxed as well. SSMS was using 100% of the server.

    Again, nothing was executing.

    Any ideas?

  • Hi,

    Is intellisense enabled?

    If it is, can you try to disable it and see if the problem persists?

  • I have disabled intellisense and testing. So far, no lagging. That is a good sign.

  • Find your \Local Settings\Temp folder and delete any .tmp files you find there. These files don't seem to clean up after themselves and after awhile you get hundreds of them and SSMS bogs down to a crawl. You may not be able to delete all of the files without closing all your local SQL server instances first, but cleaning up these files usually helps greatly.
