+Subject: [PATCH] Set TZ to avoid repeated stat("/etc/localtime")
+
+With glibc, each time the strftime() function is used (twice per process
+in a typical ps -fe run), a stat("/etc/localtime") system call is used
+to determine the timezone. Not only does this add extra system call
+overhead, but when multiple ps processes are trying to access this
+file (or multiple glibc programs using strftime) in parallel, this can
+trigger significant lock contention within the OS kernel.
+
+Since ps is not intended to run for long periods of time as a
+daemon (during which the system timezone could be altered and PS might
+reasonably be expected to adapt its output), there is no benefit to
+repeatedly doing this stat(). To stop this behavior, explicitly set the
+TZ variable to its default value (:/etc/localtime) whenever it is unset.
+glibc will then cache the stat() result.
