Performance issue

Hi all :)

Recently, I saw a mail from Avi saying that the widestring conversion
lead to performace problem.

I'm using 3.9g and I feel request takes too much time.
For instance, a single refresh (local server) takes 5 seconds and the
processor is having at leat 50% usage.
I have a pentium 3Ghz and linux. VM is 3.7-7. I also use WAEncodedKom39
but changing to WAKom doesn't really change the performance hit.

Actually, I don't know if it's a problem in my image or a more general
problem due to widestring for instance. So if you have any suggestions,
advices, please let me know...

Thanks

Cédrick

Profile it so you know where the bottlneck is.

And WAKom works on 3.9 only for ASCII characters. I someone inputs a
non-ascii character you get an exception.

ok...  so directly from seaside ?

do we have to add all times

91.5% {45ms} SUPSession(WASession)>>incomingRequest:
  |91.5% {45ms} SUPSession(WASession)>>responseForRequest:
  |  91.5% {45ms} SUPSession(WASession)>>performRequest:
  |    91.5% {45ms} SUPSession(WASession)>>start:

  |        91.5% {45ms} WARenderLoop>>run
  |          91.5% {45ms} WARender>>go

-> 45 + 45 +45 + ...?

47 tallies, 49 msec.

but it's more 4900msec for me ;)

I joined the result I add, if you can have a look and tell me important
points because it doesn't really mean somrthing to me...

Thanks

So rendering speed is not your problem. It's either the callbacks or
the network latency. The 3.9 Unix VM is said to have a greatly reduced
network latency. You can try it but I doubt it's that extreme.

I'd say invesitgate your callbacks.

I don't really know how to investigate callbacks...

Event with WACounter I have to wait around 2 seconds to update the
display ... ?  is it normal ?

No not at all. Can you try and see if the 3.9 vm makes any difference?
If you were on windows I asked if you had some kind of personal
firewall on.

ok :)
I think it's ok. With scriptaculous, submits and update are nearly
instantaneous oh maybe, I've found a reason... I had a Transcript opened, just
collapsing it improved the response time as Seaside writes a lot on it !!!

so now the counter works better (less than 1 second, I'll say half od
one) and my app too (around 2 seconds which is ok for now)...

Are there any way of improving the performance when releasing an app ?
- closing Transcript is one of them ...
