Hi James

 

Ive setup a windows 2003 guest and thought id do a performance test.

 

Nework is great, much faster.

 

When i run nbench and do an i/o test on the disk using a 100mb thread i get much slower performance using the GPLPV drivers than i do when not using them.  Is there a setting that needs to be changed?

 

Thanks

The impression I get is that before installing GPLPV, many benchmarks on Windows get "tricked" by some sort of caching effect on the dom0 side. If you try a more realistic test you will probably find that performance is actually better.
