Subject: Re: [Ofbiz-devel] Re: [Ofbiz-users] OFBiz Performance on various
app servers after optimizing OFBiz
One other thing I forgot to mention about Orion. It DOES perform better than
Resin, 1.6e6/hour compared to 1.1e6/hour, that's like 50% faster, and the
cost of both Orion and Resin is per box.
Hypothetically lets say you had a four processor box running OFBiz with
either Orion or Resin. Looking at prices at Dell (even though you can do
much
better...) a four processor PowerEdge 6400 server with 4 Pentium III Xeon
700Mhz chips with 1Mb cache and 2Gb RAM will run you pretty close to
$15,000.
I'm not SURE what the performance would be like on something like that
compared to something like the PIII 1Ghz, certainly not 15 times as fast (I
guess it could be), let's say it's 10 times as fast (to keep it easy).
In that case you would be delivering 16 million hits an hour with Orion and
11 million an hour with Resin.
So, we do our little analysis again:
Orion 1.5.3: 16million/(1500 + 15,000) = 969
Resin 2.0.4: 11million/(500 + 15,000) = 709
Weblogic 6.1: 626,400/(10,000 + 15,000) = 25.1
Tomcat 4.0.1: 216,000/(0 + 15,000) = 14.4
So, Resin is more expensive in hits per hour per dollar on a bigger server
than a smaller server, while Orion is fast enough that it is cheaper in hits
per hour per dollar on the bigger server, and it a much better deal than
Resin there, so in other words the price scales much better.
