I've noticed when I scan the processes in SysInternals Process Explorer and sort by "I/O Delta Other Bytes", my Cygwin Emacs process is almost always at the top of the list. In fact, the next processes in that sorted order are "at-spi-bus-launcher" and "at-spi2-registryd", both also from Cygwin. The total from everything else in the list, again for the "I/O Delta Other Bytes" value, is just a fraction of the total from these three processes. This is happening when Emacs is seemingly idle. I'm not sure what "Other" is, compared to read or write. At the current time, when I see it at the top of that sorted list, I don't see the disk light flashing a lot, and my cpu indicator is pretty low. Also at the current time, I have four shell buffers open, all of which are just sitting at the shell prompt (these are all that show up in "list-processes"). However, I'm constantly annoyed with performance problems on my laptop, so I'm wondering whether this is having any impact. This may be considered "trivial" or expected behavior, I'd just like to understand it a bit. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
