Indeed.
On my OS this is TERRIBLE when using "explorer" with "Web" view enabled.

If you look with an file IO utility on the host beeing browsed this way
the preformance is terible as well as every file is acces several times.

By configuring the config for "explorer" to not use Web as well as other
grapical stuff will prove 2-3 times increase in practical browsing
preformance.

I did have some logs and captures to illustrate this.

I was thinking about pacthing the IO function to give generic file data
to
explorer at firxst read with some dummy cache to realy spice up the
preformance.

I can live without icons.

Interesting stuff this, I use "Dopus" explorer replacement so
I don't have this problem right now :)

Is this attribute on file system level or in the SMB packet ?
