[Reply] HI all,
Just a quick note that if you use a PHP "accelerator", this caches the compiled PHP code ( NOT content!! ) on that server, and increases perceived performance by 4 - 10 times. That single fact plus the convenience of updating parts of the site had me leave ISAPI apps long ago. cheers gary At 11:23 on 2/07/2009 you wrote >To : delphi@delphi.org.nz >CC : >From: Neven MacEwan, ne...@mwk.co.nz >Content Type: text/plain >Attached: > >Jolyon > >> Raw byte code still needs to be interpreted - albeit translated to machine >> ops (rather than interpreted in the sense that a scripted language is). >> >> Only a compiled exe is. well. a compiled exe. > >You are on very shakey ground here, A compiler can optimise code based on >the symbols passed to it, ie the object code need not resemble to >structure of the source (famous story about benchmarks where the >"compiler" totally removed the test loop as it realised the whole process >was pointless) > >As for php, It it partially compiled afaik (partially compiled or >tokenised) and I can't see why it could not be fully compiled to a native >binary in the future (though in doing so you may sacrifice some of its >portability) as an aside the original pascal implementations were >similarly compiled into "P-Codes" whicn then ran on a target binary >runtime. > >The results were pretty much as I expected Jave and C# introduce a VM >overhead and php was propably 100% "interpreted" (actually parsed and >run), >I doubt they used an op code cache (such as apc) which can give 2 orders >of magnatude code performance increase > >Neven > > > >_______________________________________________ >NZ Borland Developers Group - Delphi mailing list >Post: delphi@delphi.org.nz >Admin: http://delphi.org.nz/mailman/listinfo/delphi >Unsubscribe: send an email to delphi-requ...@delphi.org.nz with Subject: >unsubscribe > Ref#: 41006
