Kuba,
Thanks for taking the time to test this. I've found a bug in the Linux
version that hinders performance. I think you'll see things improve a
great deal with this next minor version.
Thanks,

This is probably obvious but I decided to try this myself:
Should one run web2py with Pound on multi-core server?
probably yes if you deal with concurrent connections..
This is my config:
2.6.31-19-generic-pae
Intel(R) Xeon(R) CPU E5410 @ 2.33GHz
Ubuntu 64bit
one processor with 4 cores
disk is serial ata, with performance around this:
#/sbin/hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 268 MB in 3.01 seconds = 88.96 MB/sec
This is slow. This is one SATA disk.
I used mysql-5.1 for "writing" tests. I run it on the same machine. Also POUND.
"ab" command runs on my 32bit ubuntu laptop with 2.5 Ghz Core2Duo.
Server and laptop are connected via Gigabit ethernet directly.
I did 12 concurrent connections with 2000 calls, and then 1 connection
with 2000 calls test for every case. Application was compiled. I set
migrate=False.

db.define_table('call_attempt',Field('requestedexten'),Field('requestingexten'),Field('calltime'),Field('uniqueid'),Field('transfer_capability'),Field('context'),Field('host'),Field('tmstmp','datetime',default=request.now),Field('owner',default=1),Field('ended',default="no"),migrate=False)
controllers are(few more not in this listing):
------------
#writing
def benchmark():
return
dict(db=db.call_attempt.insert(requestedexten="123123",requestingexten="12323234",calltime="2010-10-10-17:23:32",uniqueid="123123123.123123",transfer_capability="SOUND",context="asd",host="benchmark"))
#reading
def benchmark2():
return dict(data="test")
btw I do not extend layout.html in my view, I just beautify(response.vars).
The most important thing: effects depend much on what you import.
