Hello everyone, I apologize for my poor english but I'll try to explain.
I have a strange performance problem only under Windows (via NFS on
Linux everything
works fine).
Tested operating system (Windows Server 2008 R2 64, WIndows Server 2012 R2):
First step: the webapps folder is in the standard path (eg c: \tomcat
\webapps) everything works fine and with excellent performance.
Second step: share the webapps folder (eg. c:\webapps) and change in the
server.xml "AppBase" from "webapps" to "\\servername\webapps". In this case,
despite the Tomcat service and the shared folder are on the same
server, the load
performance of applications collapse.
I've done tests also sharing folders to other servers but nothing changes.
On Linux NFS works very smoothly and with excellent performance.
Do you have any suggestions?
The TCP/IP stack on windows has lousy performance reading from a local
HD compared, to the local drive access. We used to map a drive letter
to a local drive, but found that using the subst command gave MUCH
better performance. That technique is not really applicable to your
situation, but illustrates that the TCP stack is a big performance hit.
Thanks for everything, Omar
