Describe the Bug
Every since day before yesterday, my cursor tab takes atleast a few seconds before suggesting anything. Previously it used to not be that slow at all. I have to pause my typing and wait for a couple of seconds to see any recommendations. Once I do get recommendations, the next couple of recommendations are usually faster, and then it is slow again.
If the auto complete is so slow that I have to stop typing to get it to work, there’s no poing in using it IMO. My network hasn’t changed, I am not using a VPN, my operating system hasn’t changed. Nothing has changed it on my end.
Please fix this, thank you.
Steps to Reproduce
Just open cursor and start typing. The autocomplete doesn’t work until you have paused typing and wait for a few seconds
Expected Behavior
It should provide suggestions near instantly

Hello, very sorry about this!
When this is occurring, can you open the output tab (CMD-shift-U) and select “Cursor Tab” in the dropdown. Then reproduce the issue, and paste some of the request ID’s that show up in that tab here.
Hi, thanks a lot for replying. Here’s a few logs, please let me know if this is enough

Hello I have the same problem. Cursor tab so very slow. Did you fixed it :((
You can change this setting by going to Settings → Cursor Setting → Network, and switching to HTTP/2, as shown in the image.
