--- Comment #1 from Henry Wertz hwertz10@gmail.com --- Just to add, I recently upgrades to s3ql-5.0.0 and it has a statfs cache (it stores the results for 30 seconds). The comment in the code says VSCode repeatedly makes statfs calls and it was put in to speed that up; but it's equally effective at speeding up wine's continuous use of fstatat.
