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 cygwin1-20100820.dll.bz2 and cygwin-inst-20100820.tar.bz2, but it is even worse: Cygwin.bat DOES NOT start at all and Windows complains with a message like this:

...Cannot find entry point CreateProcessAsUserW in KERNEL32.DLL...

So I have tried with the DLL suggested by Corinna in [*]: Cygwin.bat starts, but it shows the same problems I am flagging.
