On Thursday 02 June 2005 13:17, the author Vittorio De Martino contributed to the dialogue on- Tuning FreBSD with specific applications: >First of all: >I DO NOT WANT TO START A FLAME!!!!!!!!! > >On my laptop I've being using linux for some years now and "landed" at last > to the gentoo distribution which I tuned for working with the statistical > software R and the bunch of TeX programs such as latex, pdflatex, context > and the likes (this absorb 95% of my activity on the linux box). >The main action I took with gentoo was to compile everything from scratch > for my pc hardware, limiting the use of X & kde using all the above > mentioned software prevailingly in a simple console. > >Now in a partition of the same laptop I installed freebsd 5.4, set >softupdates, dma=1, and the same pieces of software as those I had installed >under linux using the ports, therefore, compiling everything for my pc >hardware, but, owing to my poor knowledge of Freebsd I'm experiencing some >problems. > >In a nutshell I prepared the following test files: > >1) a ConTeXt file full of long (useless) chapters and pictures to run with >texexec; >2) An R program which reads a long text file, puts the data in dataframes, >then loops to accomplish many repetitive mathematical calculations. > >Now running the test files in a console linux turns out to be roughly > 20-25% faster than freebsd. Particulary slow results the loop phase of the > R source code that while running slows down and seems to clog in the end. > The slowing down is also perceptible under linux but not at the same level. > >Admiring the "ordered and unitary layout" of freebsd, the logical way of >setting it up, the richness of applications, I would like to line the >freebsd installation up to the linux one, improving its performance at most, >not necessarily making it faster than linux. > >How could I obtain those improvements? What could I do to speed those > programs under freebsd? > here is a start: www.lyris.com/products/listmanager/ fox_pro/tuning_freebsd.pdf - David >_______________________________________________ >freebsd-questions@freebsd.org mailing list >http://lists.freebsd.org/mailman/listinfo/freebsd-questions >To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org" -- 40 yrs navigating and computing in blue waters.
