100% CPU usage with TeXstudio


(mehrdad moharrami) #1

I run the language tool on port 8081 using the following command via command line:

java -cp languagetool-server.jar org.languagetool.server.HTTPServer --port 8081

I get 100% CPU usage when I am using a third party app (texstudio) by java. Any idea how to fix it? It freezes my laptop and I have to use force shutdown. The problem is there for all the versions (but I believe it started after the recent release of java)

How large is the text you’re checking? Did you wait a few minutes to see if it finally finishes? I’m quite sure it would, I don’t know of any bugs that send LT into a loop. If you could share the text, that would even be better.


(mehrdad moharrami) #3

The file is large, it is 40 pages (full of formulas.) and yes, it finally finishes. Is there anyway to limit java to not use all the CPU power cause it freeze my computer sometimes and I have to use force shut down.


(Daniel Naber) #4

Not on the Java level but you can try two things:

  • Your operating system has a concept of “priority” and you can see what happens if you decrease the priority of the LT process.
  • How many CPUs and cores does your computer have? By default, LT uses all CPUs. You can try to specify -Dorg.languagetool.thread_count_internal=1 (before the -cp argument) to the command that starts LT to make it only use one CPU.

I tried what you said for a couple of days,

  • Decreasing the priority completely stop the process, I have no idea why but after decreasing the priority of java, the third-party app cannot connect to the local server anymore.
  • My CPU has 2 Cores and 4 Logical processors, so I was hoping your second method should work. After limiting LT to use one thread, I did not get any freeze (so far), but still, I have 100% CPU usage and it turns out java is using all my logical processors up to full extent. I have no idea why!

(Daniel Naber) #6

Can you post the LT server output (after having waited for some minutes)? It sounds a bit as if TexStudio is sending several requests, maybe while the old ones are not yet finished.


(Daniel Naber) #7

BTW, one way to speed up the server is using a cache. Use --config server.properties on the command line, and put this in server.properties:

cacheSize=3000


(mehrdad moharrami) #8

To make sure I am not doing anything wrong, I am using the following command:

java -Dorg.languagetool.thread_count_internal=1 -cp languagetool-server.jar org.languagetool.server.HTTPServer --port 8081 --config server.properties

and the output is the following, after running the above command:

2018-07-18 00:03:55 Not setting up database access, dbDriver is not configured
WARNING: running in HTTP mode, consider using org.languagetool.server.HTTPSServer for encrypted connections
Setting up thread pool with 10 threads
Starting LanguageTool 4.2 (build date: 2018-06-26 12:00) server on http://localhost:8081
Server started

If everything is fine, here are my observations:

  • The command Dorg.languagetool.thread_count_internal=1 has no effect at all
  • Increasing the cache size did not change anything, I still have 100% CPU usage.
  • I have 100% CPU usage, whenever I am typing in latex. Basically, even if I add/remove one letter, the java eats my CPU completely.
  • After opening the tex file, language tool takes a little while (less than 30 sec) to check everything(and meanwhile CPU is 100%).
  • The output of languagetool for the first few minutes is as follows.
  • I am not sure whether it helps or not, but from 00:25:20 to the end, I’ve done the followings:
    Remove : “the following equality is satisfied”
    Type : “the constant $\beta_0$ and the function $f(\cdot)$ satisfy the fixed point equation, i.e.,”

BTW, I removed the first few requests so I can put the output directly in here.

As you can see, TexStudio is sending a lot of requests, sometimes 7 or so per second. As some of these requests are 10KB, this will need a lot of CPU power, there’s no way around that other than TexStudio sending fewer or smaller requests.

What you can also try is adding maxCheckThreads=1 to server.properties. This should limit CPU usage to a single core. But LT will then not be able to handle all requests I guess, and you might start seeing errors in the LT output.

If you use LT for some time, there should also be lines with Cache stats in the output, it would be interesting to see those.

Thanks a lot for walking step by step towards this problem. I can see this need be addressed in texstudio and I’ve already asked the community:
https://sourceforge.net/p/texstudio/discussion/907839/thread/74b9eb62/

Adding maxCheckThreads=1 reduce the CPU usage to 50%, but as you said, it takes a long time to process all the requests and it is not “live grammar checking” anymore.

I will update with Cache stats in the following days. Thanks again.
