FreeBSD as an embedded platform

[Gerry Weaver]

Hi,

It wasn't anything exhaustive. I just ran some benchmarks on some of my code. It is mainly oriented around networking and crypto. I also noticed a difference in general system responsiveness. We have a couple of servers that we use for virtualization storage that we upgraded to 10.1 for some infiniband testing. We ended up rolling those back to 9.3 as well. I/We have not attempted to rebuild with gcc yet as you suggested. Using a stock build is preferred where possible. 

Disclaimer: I didn't intend this post to be a complaint. I fully understand the reasoning behind the tool chain switch. I'm just wondering what other folks are doing and what challenges, if any, they have encountered.

Thanks,
-G

Hi,

What performance issues have you seen with freebsd-10.1 ? You can
always compile it with the in-tree gcc compiler instead.

I started with FreeBSD 10.1, but quickly realized that the new toolchain needs to cook a while longer before the performance will be there. I then tried FreeBSD 9.3 thinking that would improve the situation. It does seem to solve the performance issues, but I'm finding that many of the third party open source libraries I would like to use either don't compile or don't run. Admittedly the last time I worked with FreeBSD was in the version 6 timeframe, but I don't remember having so many issues back then. I would really like to hear what other folks that are using FreeBSD as an embedded platform are doing in this regard. Are you using versions that are older than 9.3 or restricting yourselves to what is in the ports tree? The need to port and test a bunch of libraries would make a significant impact on pr
