I know the report explains the various cases where Racket CS is slower than Racket 7.1, but I would like to mention that these cases are very significant, at least in my case -- I mention this because the report recommends making Racket CS the default, which I am very concerned about:
> To maximize the maintenance benefits of Racket CS, it’s better to make it > the default Racket variant sooner rather than later To understand the performance impact, below are the numbers for my application. I mentioned this before [1] and I added some new timings to the Google Sheets Document [2]. * the total Travis build time (build + tests) is ~13 minutes using Racket 7.1 and it is 20 minutes, a 7 minute increase. * the build time itself grows from 3.75 minutes in Racket 7.1 to 8.5 minutes in Racket CS, a 5 minute increase. My Edit-Compile-Run cycle is already slow with Racket 7.1. * even ignoring compile and load time, code sections which run after Racket initialization and library loading indicate that the running time is increased by 33% -- given that current execution time is several seconds to several minutes in Racket 7.1, a 33% increase is very visible to the end user. As it stands now, the cases where RacketCS is slow have a significant impact on my application. Do others see the same performance degradation in their applications? Best Regards, Alex.
