Subject: executing commands is VERY slow (redux?)
Encoding: 8bit
From: "Paul S R Chisholm" <dtjta3402 AT sneakemail DOT com>
Message-ID: <28634-24938@sneakemail.com>

I've been using Cygwin on a particular laptop for months, with
great success. Then, suddenly, one day, it took thirty seconds
for me to get a login prompt. I soon discovered that Cygwin was
suddenly taking at least a second to run any command:

local$ time /bin/echo


real    0m1.333s
user    0m0.030s
sys     0m0.030s

local$ time date
Sun Feb 20 23:28:37 EST 2005

real    0m1.976s
user    0m0.020s
sys     0m0.050s

The problem occurred overnight. I didn't change anything
relevant (though I can understand your skepticism). The problem
comes and goes; it happens most of the time.

This appears to be similar to a report discussed on this list
beginning 2002 July 25. I don't see a resolution in that thread.
The thread suggests running strace. When I do, one or two
obvious things jump out, depending on how I run strace and how I
search the results; see below.

I don't have network shares in my PATH. I see this problem even
immediately after running setup.exe to get the latest versions
of the Cygwin software. Below (after the strace output), you'll
find a bunch of information on what I'm running. (I've changed
my user ID to "nobody" to avoid it falling into the hands of
spammers.)

Any thoughts?
