Hali,
Erdekes ez a HotSpot futas idoben optimalizalasa, a Sun hibbant agyu
managerei lehet kitalatak ilyet es a fejlesztokkel csinaltattak vmit
legnagyobb fajdalmaik ellenere. Eleve halott dolog az egesz. Lehet nincs
is ilyen benne, csak megy a nagy suket marketing duma es vannak sajnos
akik elhiszik.
Ha jol emlexem Auth Gabor azzal ervelt, hogy ez azert jo, mert ha
valtoznak a korulmenyek, akkor a megvaltozott korulmenyekhez
hozzaoptimalizalja a kodot.
Na de honnan tudja az a HotSpot, hogy milyen gyorsan fognak valtozni a
korulmenyek?
Lehet, hogy eszbekap, hogy hopp most ken kicsit atoptimalizalni a kodot,
mert mar 10 perce ilyen az input, erre amikorra mar atoptimalizalta mar
megint olyanok lesznek a korulmenyek, hogy nem a legoptimalisabb lesz az
atoptimalizalt kod. Aztan kezdheti elorol, felesleges tulbonyolitas, tobb
veszteseg van belole, mint elony.
Vagy van ebben a HotSpot modulban egy Sun Nostradamus Future Seeing Layer
(SNFSL)? Aztan meg van valami ilyesmi szoveg a dokumentacioban:
Sun's state of the art excellent quality HotSpot technology makes it
possible to provide the best byte code execution speed in any cases.
HotSpot's just in time compiler is able to recompile Java byte code into
native machine code whenever the environment requires it in order to gain
higher execution speed. In order to provide ballanced teamwork of the just
in time compiler and the compiled native machine code, the HotSpot
techology have to know what situation will happen in the future, because
this is the only way making possible to precalculate that optimal time
point when the recompiling must be executed. The aim of our Sun
Nostradamus Future Seeing Layer is to provide information from the future
to the just intime compiler. This layer knows about anything, it is in
direct contact with the operators mind such as with the stock-market. The
Sun Nostradamus Future Seeing layer doesn't preestimate the future based
on current data and preestimation algorythms, because this would consume
significant processor time and would reduce the available internet
connection speed. Rather Sun developers, whom the most talented developers
all over the world, swimmed the design plan of Sun Nostradamus Future
Seeing Layer in pure SPICE at the earliest phase of it's preanalysis phase
in the sixtees. Due to it's early meet with the world's most potent
consciousness expanding substance it is always able to become one with the
Universe/God/Brahman. This unique revolutionary technology from Sun makes
possible the following things:
- Sun Nostradamus Future Seeing Layer does not consums processor time, so
it can determine the right point of byte code recompillation in zero CPU
clock cycles
- it is even does not contain any single line of code because it is the
part of our subconsciousness, so Java developers and users experiences the
farly reduced memory consumption in their daily life
- the recompilation of the Java byte code does not consumes any CPU time
too, because Sun Nostradamus Future Seeing layer exports the compilation
after that time when our know world is no more exist, after the
compilation will have finished in the far future it imports back the
native machine code to now, to the same time of the compillation job
exportation
Sun's mission is to provide you the most potent platform independent
technologies, it runs on Sun/Solaris, x86/Solaris, x86/Windows and all
Linux platforms. If you want to use your enterprice system on your mobil
phone it is no matter, since most mobile phones are equipted with Java
Runtime Environment which makes it possible to migrate softwares from
super computer clusters into your phone without any painfull porting
issues.
Based on the above explanation we can say that we have developed the most
advanced computing technology all over the world. Java, the most excellent
programming language is just get better. It farly outperforms C and C++
and even the hard wired application specific integrated circuits.
Todays successful buisness life is unimaginable without Sun's Java
technology. For competetive buisness operations it is a must to use Sun
products.
By using Sun products your cock will be also longer by 4 inches and wider
by 1 inch. This is the true and only way to find the most sexy and
beautiful secretaries in the job market. Those pretty girls will be so
keen on you beacuse you are using the products of the worlds coolest
company which is of course the Sun. Beleive it or not it will be not easy
to you stop those girls wanting sucking your dick all the time and making
love with you. Once you have bougth a Sun product you will be
overwhelming. It is the only way for success! Buy it know!
Kicsit felporogtem. Mar regen hallottam ennyi hulyeseget egy nap alatt,
amennyit az Auth Gabor osszehordott. Meg a volt cegemnel sem hordtak ennyi
baromsagot ossze a managerek, pedig ott Sun-t hasznaltak :)
Ki fog meg itt derulni, hogy a Java meg az ASIC-oknal is gyorsabb meg
mobiltelefonon is :)
udv.
