Visual Studio 2013 has a package server running  and it was spending up to 2 million K of memory   I put it to low priority and affinity with only one CPU   and Visual Studio ran much more smoothly

If you are debugging an ASP NET website using Internet nbsp Explorer nbsp 10  and later   make sure to turn off your Internet nbsp Explorer  LastPass  password manager plugin  LastPass will bring your debugging sessions to a crawl and significantly reduce your capacity for patience   I submitted a support ticket to Lastpass about this and they acknowledged the issue without any intention to fix it  merely saying   LastPass is not compatible with Visual Studio 2013

Visual Studio Community Edition was slow switching between files or opening new files  Everything else  for example  menu items  was otherwise normal   I tried all the suggestions in the previous answers first and none worked  I then noticed it was occurring  only on an ASP NET MVC 4 Web Application  so I added a new ASP NET MVC 4 Web Application  and this was fast   After much trial and error  I discovered the difference was packages config - If I put the Microsoft references at the top of the file this made everything snappy again     Move the Microsoft  entries to the top     It appears you don   t  need to move them all - moving say  lt package id  Microsoft Web Infrastructure  has an noticeable effect on my machine   As an aside   Removing all contents of the file makes it another notch faster too  Excluding packages config from Visual Studio does not fix the issue A friend using Visual Studio 2013 Premium noticed no difference in either of these cases  both were fast    UPDATE  It appears missing or incomplete NuGet packages locally are the cause  I opened the Package manager and got a warning  Some NuGet packages are missing from this solution  and choose to Restore them and this sped things up  However I don   t like this as in my repository I only add the actual items required for compilation as I don   t want to bloat my repository  so in the end I just removed the packages config   This solution may not suit your needs as I prefer to use NuGet to fetch the packages  not handle updates to packages  so this will break this if you use it for that purpose

In the case of web applications  another cause of slow building and debugging  but not IDE navigation  could be the Browser Link feature   I found that with this switched on  building would take 4 times longer and debugging was painful - after every postback  web pages would freeze for a few seconds before you could interact with them

I had a Visual Studio behavior where the typing was slow for my HTML files  Previously when I installed  I guessed that because my HTML files were generic HTML that the need to install any web development tools from the workload component of the installer was unnecessary  I went back and installed this bit and Visual Studio behavior became as I expected it

Try to set Current source control plug-in to None  menu Tools  rarr  Options  rarr  Source Control   if you are using the Microsoft Git provider  which seems to slow Visual nbsp Studio nbsp 2013 down more and more the larger the repository gets     I had the whole Dojo Toolkit framework under source control using the Microsoft Git provider  and it got to the point where there were delays from the time I hit a key to the time the glyph would appear on the screen  That bad   When if you need Git again  you can switch to the TortoiseGit provider or Git-Extensions  both will work without slowdown  I like Git-Extensions  personally

I had a Visual nbsp Studio nbsp 2013 installed  and it was running smoothly  At some point it started to get sluggish and decided to install Visual nbsp Studio nbsp 2015  After install  nothing changed and both versions were building the solution very slow  around 10 minutes for 18 projects in solution    Then I have started thinking of recently installed extensions - the most recent installed was PHP tools for Visual Studio  had it on Visual nbsp Studio nbsp 2013 only   I am not sure how can an extension affect other versions of Visual Studio  but uninstalling it helped me to solve the problem   I hope this will help others to realize that it is not always Visual Studio s fault

None of the suggestions worked for me  but I did solve my problem  I had tried most of the other recommendations before coming to the following solution   My Scenario Problem   Using Visual nbsp Studio nbsp 2017 with ReSharper  Ultimate  Keyboard input in the IDE got super slow as others have described  The last change I made to my solution was to add a new web site project  so I looked into that  After trying a lot of things  I tried adding a second web site project  so I could try to replace the first one  and Visual Studio just tanked after that  It wouldn t even load the solution anymore   My Solution   I forced Visual Studio closed and then I removed the newly added web site project s  from the  sln file using Notepad  After saving and starting Visual Studio  my solution loaded quickly and everything seemed to be back to normal  I added a new Web Site with a slightly different configuration  see the thinking below   and the problem did not present itself again   My Thinking   I think the problem stemmed from creating the new web site project and using a file system path to a network share that is hosted in Azure  I m working over VPN which tends to slow things down  and I occasionally experience various routing problems with some services  so my problem solution might be a bit of a snowflake  I changed the file system path to be a local repository and will publish the files as needed which seems like a much better way to go
