Resharpers intellisense is slow compared to Visual Studio's
Hey guys
Account holder for a year and a bit now.
Me and a colleague both have issues with Resharpers Intellisense being a little too slow since we've first got it. The simplest example is typing out the following line of code:
"bool test = f"
and hitting return.
Here is what it looks like with the Resharper Intellisense - return is treated as line break.
And here, with Visual Studio's Intellisense - return triggers auto completion of false.
We hit this issue surprisingly often - our only option is to slow it down a bit (type in a few extra letters - 'fals' - then return.) In the 'heat of the moment' though, we'll often hit return too fast which'll cause us to stop, backspace, type in a few more letters ('als'), wait briefly for the popup and hit return. It's a little thing. We only need to wait a little while (fraction of a second) but it is long enough for resharper to miss lots of autocompletions.
I used a simple boolean as an example, just to show that it isn't caused by accessing a class bloated with member variables and methods (which might potentially cause Resharper to chug) - This is just a simple boolean.

Maybe it will help if you set the option "Automatically show parameter info in milliseconds" to zero. You will find it in "Environment/Intellisense/Parameter Info". Normally R# waits 50 millisconds before the intellisense popup is shown.

Thanks for the reply.
"Parameter Info/Automatically show parameter info in milliseconds" was already at 0 on both of our machines, so that doesn't seem to be the issue.
Hello Timur
Please collect a performance snapshot as described here https://resharper-support.jetbrains.com/hc/en-us/articles/207243205-How-to-collect-a-performance-snapshot-and-send-it-to-JetBrains-Team and send it to us.
Thanks!
Here's another example. Happens on all projects for me:
Typing too fast consecutively causes completion to never actually show, no matter how long you wait.
I am also having this problem. Resharper 2017.1.1 on VS 2017 (but this problem has been around for at least a year). I have sent a performance snapshot and am happy to help further debug.
I tried submitting a performance snapshot via Resharper's Problem Report, but I got an error so instead I uploaded the performance report to ftp://ftp.intellij.net/.uploads. The filename is "Wynexuk.zip".
In the snapshot, I type "this." over and over again (deleting it after each try). If I type at my natural speed (and I am not a particularly fast typist), Resharper's intellisense never appears, even after typing the dot. If I slow down my typing, then Resharper's intellisense will properly appear mid-"this" and properly update after typing the dot. (To be clear it's not just a problem when typing "this" -- it happens when typing pretty much anything.)
My "start automatic completion on typing after" setting is set to 10ms. (It was 50ms and I lowered it in an attempt to fix this issue, but to no avail.)
Please let me know what more information I can provide. I'm happy to help debug.
@Walt I filed a new request on YouTrack https://youtrack.jetbrains.com/issue/RSRP-464364 to investigate the snapshot file you'd sent us
Thanks!
Any updates on getting this issue fixed?
I'm interested in this as well. I seem to have the same issue being reported here. It is disruptive enough that my R# license is currently not being used as having it active is too detrimental to my workflow.
Hello @Mscranton!
Sorry to know you experience inconvenience with ReSharper.
Could you pleasecollect a performance snapshot as described here https://resharper-support.jetbrains.com/hc/en-us/articles/207243205-How-to-collect-a-performance-snapshot-and-send-it-to-JetBrains-Team and send for us so we could investigate it.
Thanks in advance!
Same issue here. Intellisense not showing after dot. When i hit Ctrl+Space intellisense shows but too slow (abt 1-2 secs) late.
Just uploaded my performance snapshot.
Please advise.
Thanks
Rupert
Hello Rupert!
Thank you for the provided snapshot.
Please follow the issue in our tracker to get the latest updates on the problem - https://youtrack.jetbrains.com/issue/RSRP-466386.
Thank you.
I have the same issue. Except for it takes a couple of SECONDS before ReSharper shows the IntelliSense. I'm desperate at this point. I repaired the Visual Studio installation, that fixed the issue - No Resharper was installed. Now I installed ReSharper to visual studio and problem is back. It drives me nuts..
Hello @Vmachacek!

Thanks in advance!
I did that..
Now I see the yellow bar saying Extension Resharper likely to cause 8 seconds of unresponsiveness. And VS prompting me to disable it
Hello Vojta!
Could you please specify issue ID of the submitted snapshot?
Thanks in advance.
