I have finished setting-up a simple development environment with my Indigo2 (nfs shares, telnet server, bash basic configuration, vim and some other tweaks) in order to start doing some software ports. Since I'm mainly involved in C= related projects, I've told myself: "why not going retro also for retro devel tools"?
I've started with something really easy, pretty much like a simple recompilation. The software is named TapClean, which is well known by people who try to preserve tapes from the old C=64 (I've also used it a lot of times with my tapes collection). It turned out to be a software written in C very well... but is also slow as a hell in analyzing and "cleaning" the tapes. Here is a stripped output of a "cleaning" run of a .tap file created by me...
Code:
trantor [ ~/irixnfs/tapclean/src ]$ time ./tapclean -o 0208\ -\ tcgames4a.tap

It took nearly 40 minutes to clean the .tap on my Indigo2 vs 52 seconds on my i7 macbook pro 2015
Clearly this tool is nearly unusable on SGI, but for the sake of completeness (or benchmarking
), if anybody wants to download the attachment, try it with this command:
Code:
time ./tapclean -o 0208\ -\ tcgames4a.tap
and paste its system cpu and the last three rows with real/user/sys time, it can give me and idea on how different cpus perform vs my IP22 R4400@150Mhz teal indigo.
