Howdy,
I have been working with one of our developers to port a Linux application to
opensolaris. While benchmarking the app, we noticed that it ran 2x slower on
a Nevada build 85 host than it did on Linux. The application utilizes libxml to
transform XML documents, and I think we have narrowed do

ok, i see.
Then, how can I correct this problem when using prstat?
Or is there any other statistics tool that could catch these short lived
processes correctly?
If your using Solaris 10 or Nevada, you can use shortlive.d from the

Hi Richard,

Are the events documented anywhere by any chance? Is there anything
equivalent to "dvma_bytes_xfr" to get the number of bytes transmitted

Thanks for any insight,

Howdy,
While reading through Solaris Internals this weekend, I came to the
section on UFS direct I/O. The book states that random and large
sequential workloads benefit from direct I/O. Does anyone happen
to know how big a "large sequential" I/O needs to be to benefit from
direct I/O? Are there a
