uninformed optimism
I've now clearly hit the uninformed optimism phase of my stay at S1.
In today's training (reely aimed at operators and therefore quite, uhm, simple[1]) we looked at Postilion Postcard which is a very cool thing.
The technology is solid and fast - not like J2EE kinda-fast, really fast.
Postcard runs in a Java VM together with the Postilion core (named Transaction Manager) and together they consume aruond 11MB of memory and will (on a standard desktop PC) process in the region of 60 transactions a second[2].
Compare this to the SAP J2EE app. server which wants around 2GB of memory to slosh around in. Of course the workload is different, but still...
[1] it includes a section on checking free disk space :P
[2] amazing how much you gain by working with pure binary protocols and highly optimised algorithms rather than something nasty like XML[3]
[3] which, I must admit, I still think is the best tool for what it's meant to do
