I've been looking into fsync calls made by Firefox to understand how efficient it is with regards to filesystems.
strace to track the fsync calls made by the threads of Firefox over a browsing session and here's what I've found,
Total number of calls made
Calls made by each thread
Though Firefox created ~90 threads over the session, only 12 made
Now how do I go about finding the specific function of these threads? Like, is the thread a tab, or is it some background Firefox process? Where should I start looking?
Rephrasing the question to help anyone out in the future, how do you find the specific function of a Firefox thread?
