Results for User Mode Process LYX-QT4.EXE (PID = 3344)
User Time = 15.07% of the Elapsed Time
Kernel Time = 11.18% of the Elapsed Time
Total Avg. Rate
Page Faults , 5692, 95/sec.
This looks highly suspicious and could be the reason why the csrss.exe
program is taking all the cpu.
I don't think so. Compared to Linux, Windows trims the working sets of
processes quite aggressively, which can result in a high number of page
faults. However, the freed ages are not actually removed from RAM, but
moved into the system cache and restored from there in case of a page
fault. Hence, a high number of page faults does not automatically imply
performance problems.
Moreover, this data is from the Lyx process and not from CSRSS where,
AFAIR, the CPU clocks are actually eaten. The only thing I can see is that
the process spends most of its time in the QtGui4 module, which in turn
might well lead to a high number of interactions with CSRSS.
Could you provide the results for the CSRSS.EXE process as well?
As a wild guess I would assume a problem with some QT constructs
interacting badly with Win32 User/GDI. I have this slight feeling I had
seen similar problems with other QT applications on Windows, but I am not
really sure.
