Currently at 3-4msec as measured at the Rich Client decoder (JAX-WS) after
upgrading to AMD64 X2 5200+. Using JBoss 4.2.2GA and JDK 1.6.0_07. Apache is in
front of JBoss and access logs indicate 0usec for about 90% of the requests.

Thanks PeterJ what you said does make sense. I will hold off a while longer on
trying JBoss 5b4 until the production release.

Has anyone compared Jboss5b4 performance versus Jboss 4.2.2GA using the same
app?
I am curious I am getting 4-5msec response at my java client time using:
Server- JBoss 4.2.2GA using Java 1.6.0_05 and JAXWS 2.1.3 on Windows 2000
professional with AMD64 X2 5200+
Network - 1Gbps
Over the internet
I have not spotted any type of access logs for JBoss. Is there such a thing?
Other app servers have them.
Thx,

Okay I figured it out. Appears since JBoss binds to localhost that even though
my apache instance is running on the same machine I needed to specify localhost
in my httpd.conf rather than the IP of the address of the server JBoss is
running on.
Really odd but it works.

Hi All,
For some reason JBoss 4.2.1.GA is rejecting connections from Apache via ajp.
This does not occur in 4.0.5.GA. I would like to upgrade to 4.2.1.GA. Is there
some new security setting in 4.2.1.GA? My Apache Server is running on the same
physical machine as JBoss and it is version 2.4.

Hi,
It seems like 128m is enough memory for most implementations.
Yes supply a stack trace. You could also try jconsole to monitor JBoss and see
if it shows how much Perm space is actually used.
The other thing you might do is check the bug fixes for 4.0.5GA to see if there
is any memory leak
Hi All,
Sorry for being away so long. Been busy working on the front end of the web
system that uses JBoss for the app server. Was able to release the system today
and some information can be found at theserverside.com at:

Final Hardware Upgrade.
Upgraded finally from AMD64 3800+ AM2 to AMD64 X2 4200+ AM2. Everything else on
the motherboard stayed the same.
My JBoss startup time went from 18seconds to 14seconds or 22% improvement.
Just further proof that the startup time is CPU bound.

Hi All,
I tried some testing regarding the time it takes to start JBoss and I am
getting 18 seconds on a AMD64 3800+ AM2 1GB DDR2-800 on Windows 2000
Professional. I am loading a big EAR (9MB) because of inclusion of Web Services
jar for JAX-WS.
I set up a RAM Drive and put JBoss on it but I s
Good Morning,
Over the weekend I was able to come up with a simple light weight cache that
got me what I needed that was beyond a HashMap in simplicity yet the
performance was in the nanosecond or picosecond range (0-999 picoseconds) I had
a problem measuring the execution time since it had a t
Okay, Learned something new last night. My logins are actually below 1 usec
because the timer System.nanoTime() in my timer class was taking 1.072 usec.
I am working on a solution for caching that looks like I might get down to the
40-50 nansecond range for the cache. then hopefully I will be do
Okay I am down to 2usec for logins and 7-8 usec for most everything else in the
servlet layer of TomCat/JBoss in 32-bit mode.
Looking at AMD64 X2 4600+ AM2 to replace AMD64 3800+ AM2 but probably better
off with AMD 62 FX that has 1MB L2 cache instead of the 512KB cache.
Have fun all.

Hi All,
Finally upgraded last night from Intel P4 3Ghz (Northwood core) DDR400 to AMD64
3800+ AM2 DDR2 800 early in morning today (2:00AM).
Quickly ran test and was getting little over 5msec total transaction response
time over internet for single hop short distance was 7-8msec before upgrade.
Hi Pramod,
Thanks for the comment. I am on vacation right now but checking this thread.

Hi All,
Just wanted to mention I am using JAX-WS 2.0 for my web service layer. Even
though it is a reference implementation it still has been fast compared to
axis. The important thing to know about Web Service layers for performance are:
1. Use fast infoset.
2. Use Document literal
3. Use

Okay,
More about networks. For internal users you might want to check out extended or

for internal sites where you have gigabit lan where the client and server
