No, that wasn't the intent. The fact is, a single C based client can
generate 25 times more authentications/second than a single slamd client.
So, that would mean I could use 75% fewer clients if I could use C, to
generate a similar load.
The whole point to load generators is to increase the number of them as
needed to
blast the server with as much load to saturate it. If one load injector
is not sufficient then
increase the number. SLAMD does the job nicely.
Well, actually, it is a little more than that. The more clients you put on
a single system, the worse things get. I currently use 5 systems with 4
clients each, for a total of 20 clients. Fewer servers with more clients
performs worse.
One of the advantages to SLAMD is it's simplicity and the fact that it is
a platform. It's easy to write
quick tests using Java and load them. If you want to write a C based
platform that's just as easy to use
to do the same thing then be my guest. However I don't think it's going
to go that far.
I would hope it would be built with some type of test template engine. In
any case, certainly none has been written so far. ;) I'm just always on
the lookout for something else.
