Hello again. Recently I measured the perfomance of web2py regarding to 'milliseconds per request'. Got some unexpected results. The most slow part of the application is the model. It takes 40-60% of total time. Measurement was done simply by putting import time;print time.time(),'model start' at the beginning of db.py and similar line at the end of it. Here is what it produces on my laptop (Turion64, 1.6GHz, 1.5G RAM):
1244187446.32 model start 1244187446.62 model stop 0.3 second just to set up the model! I can live with 0.05 for it, may be even 0.1, but 0.3 for _each_ GET or POST request is a bit too much, don't you think? That is for not too complex model - 17 tables, averaging 8.6 SQLFields per one. On another web2py project it takes 0.38...0.42 second each time :( I tried compiling my app and measuring again: 1244187625.31 model start 1244187625.69 model stop Not any better. In fact, it's even worse, but since results vary from run to run I suspect that it is just the same perfomance. Massimo, as I know you've been working on new model for some time already. Is there any hope of having a faster model? I suspect more lazy evaluation should do the magic, but I didn't do any research yet. Frankly speaking when I first discovered the fact that web2py always _executes_ model, controller, view, I thought that it may be a perfomance hog. Until I actually did that check I thought that it will execute db.py each time it changes on-disk and then just keep built structures somewhere around, probably pickled. May be it is still possible to use that approach to some extent? Or may be I am just completely missing the point.
