I have a directory (500MB, 30 files) which contains mainly 'exe' (setups for TB, FF, OO etc.). If I try 'ls -l' in this directory, the first time it take about 30 seconds to list the files. After the first time, the listing is almost without delay. The same happens also with 'ls -l /usr/bin'.
When there is the 'hang' (30 secs.), Task Manager shows that AVG9 takes about 50% of CPU: this occurs *only* with 1.7.6 but _not_ with 1.7.5, with which 'ls -l' is almost immediate, regardless of the number and type of files.
Obviously I have tested this, each time, with a 'fresh machine', to avoid 'cache' effects.
The system is WinXP SP3, AMD Athlon 64X2DC 2.03GHz, 1.75GB RAM.
Try a recent snapshot:
I have tried cygwin1-20100822.dll.bz2, but same results. :(
The first time (no cache 'effects') I do
$ time ls -lrt /usr/bin
the results are:
CYGWIN_NT-5.1 1.7.5(0.225/5/3) 2010-04-12 19:07 i686 Cygwin
time ls -lrt /usr/bin
CYGWIN_NT-5.1 1.7.6(0.230/5/3) 2010-08-16 16:06 i686 Cygwin
CYGWIN_NT-5.1 1.7.6s(0.231/5/3) 20100822 02:25:11 i686 Cygwin
