Hi,
Has anybody benchmarked the speed of a DJGPP 1.10+ program running
under VCPI and DPMI to gauge the relative efficiency of the two
techniques? The author of a PD app. built using the Intel 386/486
code builder that I evaluated recently, claimed that his DPMI version
was ~1.5x faster than the VCPI version. Any comments?
Secondly, the FAQ for DJGPP states (if I understand it correctly) that
up to 128 Mb of memory and 128 Mb of virtual memory can be allocated
giving a grand total of 256 Mb. Is this a theoretical calculation or
has this actually been tested and verified? What was the PC setup
that was used during the testing/verification (mem manager, config.sys
and autoexec.bat)?
Thirdly, if I remember correctly, a recent Computer Langauge issue
(June?) reviewed GCC (not quite DJGPP) along with several other major
league C/C++ compilers. It would be good to see a good comparative
study of DJGPP, EMX, Microsoft C, Watcom C, Borland/Turbo, Zortech
etc.
Regards,
Tony.
