: Because as I said - the method dispatch and the overhead of the mod_perl
: handler takes over. multi-print is the only one that has to call methods
: several times. The rest are almost equal.
:
: This also demonstrates some of the value in template systems that send all
: their output at once, however often these template systems use method
: calls too, so it all gets messed up.
This may be veering off topic - but its been on my mind for a while now ....
Apart from thanking Stas for his benchmark work, which I find very
interesting (does he sleep ;-) - this and few few others (benchmarks) have
all touched on the area of including mod_perl output within HTML. I have
always wonder what everyone else is doing on this front.
I usually suck a template into memory (one long line) - usually done at
startup. I then create all the conent with either pushing onto an array, or
.= string concatination. Finally I regex the template - looking for my tags
and replave those with output. Needless to say that one page can onsists of
many templates (page or inside of table (bits from <tr> </tr>) etc ...).
>From Stas previous benchmarks I've preloaded the mysql driver and now
usually use the "push" onto array to prepare content - Thanks Stas.
Who does everyone else do it ? Can this type of operation (that everyone
must do at some time) be optimised as aggressively as some of the others ?
Yet still keep the abstraction between design and content.
