Michele, Jonathan, Bruno, Anthony and I have continued test possible ways
to improve web2py code.
We have lazy tables in trunk and they can increase the speed of your
code a lot but require minor rewrites of models.
We are also looking at ways to improve the speed of your code without any
rewrite and we have some important changes in trunk.
They really need to be tested to make sure they do not break backward
compatibility.
accessing:
request.<anything>
response.<anything>
session.<anything>
as you can imagine this is everywhere. this is a major bottleneck. We made
it 2-3x faster
accessing:
db.<tablename>
we made this 2x faster
accessing:
db.<tablename>.<fieldname>
we made this 20x faster (not a typo, 20x)
Given row = db(db.table).select()[0]
accessing:
row.<fieldname>
This is also a major bottleneck. We make this 10x faster.
WE NEED TESTERS. Does the latest trunk/nightly built break your app?
WE NEED INDEPENDENT BENCHMARKS AGAINST 1.99.7. Here is the code to
benchmark:
-------------
import time
db=DAL()
db.define_table('person',Field('name'))
db.test.insert(name='one')
n = 100000
t0 = time.time()
for k in range(n):
y = db.person.name
print (time.time()-t0)/n
row = db(db.person).select().first()
t0 = time.time()
for k in range(n):
y = row.name
print (time.time()-t0)/n
