Re: [Htt-users] Load test and benchmarking

[Christian L. <li...@gm...>]

Hi Dossy

Thanks very much. No currently there is no defined process for httest 
development. If you have a usefull patch feel free to send me that. The 
module concept in httest makes it relativly easy to add new 
functionality blocks :)

I currently up work the syntax and make it more flexible, would be 
httest 3.x. But I do not have plans when to launch it and how to 
read/migrate old scripts.

I think many stuff you want have is allready there:

* shared variables

GLOBAL yourVar yourVar2
GLOBAL yourVar3

CLIENT
_SET yourVar=foo
END

CLIENT
_SLEEP 1000
_DEBUG $yourVar
END

* Init blocks could be done this way

CLIENT
# do what ever you need to start with your tests
END

GO

#now start your tests
CLIENT
...
END

* Performance Tests:
I think httest is not the fastest on the market, needs a lot CPU power :(

But with the
     PERF:DISTRIBUTED <host>:<port>
     PERF:RAMPUP <clients> per <interval>

you could even distribute and ramup your clients (Rampup even works 
distributed). But it is a little quricky this distributed thing. Please 
have a look into the test folder within the tar ball. You will find 
there many examples how a command could be use, just grep the command ;)

I hope that helps.

Best regards
Christian
