3 years ago Oops sorry for the delay. In the interim some other change appears to have fixed the issue. (I tested in emacs -Q so I know it's not my config). If this ever comes back I'll reopen.

3 years ago Actually, perhaps it is not fixed.
Setting lsp-print-performance to t and reading the lsp-log gives thousands of these:

Seems like your config is off: check this - https://emacs-lsp.github.io/lsp-mode/page/performance/
PythonNut
commented
3 years ago The only setting in my config that isn't at the recommended value is probably my gc-cons-threshold. However increasing it does not cause the CPU usage to decrease. Garbage is collected less frequently, but each collection takes much longer. Tuning gc-cons-threshold can, at best, mask the root cause which is that very large amounts of garbage are being produced, even though I am simply letting Emacs sit with no user input.
Interestingly, if I do actually start typing or scrolling, the CPU usage decreases, Additionally, there does seem to be some nondeterminism involved, since I cannot always reproduce this issue.

commented
3 years ago I just want to clarify since my wording may be misleading: The root cause is not a performance problem, it's some sort of miscommunication with texlab which causes the language server to go into an infinite loop where it spams Emacs with textDocument/publishDiagnostics requests as fast as it can.

3 years ago @PythonNut Hi, apparently I was having the same issue as you did. I tried a few different things, then saw this issue and indeed compiling and installing #408 fixed all the problems for me.

3 years ago Based on the previous comment I am marking the issue as closed. Please reopen of this is not the case.
PythonNut
commented
3 years ago @lucasvreis that's great thanks for the heads-up. I am running Texlab 3.0 now and indeed everything is running smoothly now. I suppose this comes as no surprise since they added debouncing for the messages we were previously getting spammed with.

6 months ago Hi @PythonNut and @yyoncho.
I had this issue in, and it first seems a problem with texlab.
I reported upstream, and the author made a fix for the issue. With eglot everything is working fine (https://github.com/latex-lsp/texlab/issues/986)
However, if I use lsp-mode, I have the same high CPU behavior. I'm getting a lot of these
[Trace - 12:49:34 PM] Received notification 'textDocument/publishDiagnostics'.
Params: {
"diagnostics": [],
"uri": "file:///Users/maikol/Library/TinyTeX/texmf-dist/tex/latex/base/atveryend-ltx.sty"
}It seems lsp-mode goes recursively to the TeX distribution looking for issues. I have numerous issues in flycheck related to those files.
WDYT?
Best.

that is not something that lsp-mode does, but something that the server does based on the project root selection. If the perf is bad on emacs side please include the perf report as reported here: https://emacs-lsp.github.io/lsp-mode/page/performance/#reporting-performance-problems

5 months ago Hi! @yyoncho. I'm sorry it took me so long to reply.
Below are some diagnostics that I am receiving with lsp-mode. This problem was found in https://github.com/latex-lsp/texlab/issues/986 for a lot of packages that were loaded.
Also, here is a report on the CPU profile when my machine got frozen.
Best.

Describe the bug When using the
texlablanguage server (for LaTeX) with theflycheckpackage, Emacs consistently uses 100% CPU, although it does not freeze. Additionally, if you enable I/O logging, you will see that there are lots of messages being exchanged with the server.To Reproduce Open a
.texfile (even an empty file will work) and runlspwhenflycheckis installed. You will needtexlabinstalled andlsp-tex-servershould be set to'texlab(i.e. the default).Expected behavior If the user is not doing anything I would expect the CPU usage to die down after a while.
Which Language Server did you use
texlabas defined inlsp-tex.el.OS Arch Linux
