cygwin very slow under virtual box (productivity hit)

cygwin very slow under virtual box (productivity hit)

[J.V.]

I have Windows XP Pro x32 in a VM with the latest version of cygwin 
installed.

When I open a cygwin bash shell, and type '$ls' it just sits there forever.

Any other command I type is freakishly slow.  How do I get this to run 
faster under a vm environment.

I am not sure why it is taking so long to do a simple ls or mkdir or any 
other command.

Even if I $vi a file it takes a while seriously cutting into the 
productivity gains that cygwin on the host environment provides.

Is there a commercial version of cygwin or the likes that I can lay down 
cash for to go fast under a VM environment?
I need to get this going or dump it all together for something else, 
work has slowed to a halt.

I use Cygwin in a (VMware Player) VM with XP all the time and it's not
like you describe at all. I think the main Cygwin developers also use
VMs (at least from time to time), so there's nothing intrinsic to
running in a VM that causes the performance you describe.

I can't say for sure what your problem is, but I'd start by checking
your PATH for any directories on a remote machine (including any "host"
directories provided by your VM software). Or, perhaps simply try

  $ PATH /bin /bin/ls

and see if your problem goes away.

If none of that works, follow the directions here:

No.

That should read:

  $ PATH=/bin /bin/ls

and just to be clear, the "$" is the prompt character. Don't type it.

as usual, plz, remove bash-completion...

cygwin.com/faq/faq-nochunks.html#faq.using.slow

also, plz, could you complete the FAQ about that, thanks in advance.

something like :

alternative, remove the bash-completion package if any.

Wouldn't it make more sense to find out what part of the bash-completion
package is the usual culprit and to disable or change this part in a
bash-completion package update?
