I develop with maven/netbeans/openjdk in Java and Groovy on FreeBSD 9. That works. There is no profiler support in netbeans. And the JVM can't request huge memory page (may be this is fixed in 10?), so it could perform better : http://www.oracle.com/technetwork/java/javase/tech/largememory-jsp-137182.html Java is much slower than other apps when the box is busy (building a world for example) but I'm not sure if this specific to FreeBSD.

Any performance improvements of targeted binaries? Nope, because you can't just ship a full list of packages for a full list of processors on the given architecture. You can build your world/packages though adding -march=native to CFLAGS. 10. How is the Java ecosystem on FreeBSD? Is LLVM specific to applications? I make the assumption that the VM in LLVM is referring to something like a JVM, for code abstraction. No, LLVM is rather a backend with a lot of copmiler and toolchain stuff. There's a Java/.NET rewrite using LLVM named vmkit and I think JVM there is almost functional. But it's not even in the ports. -- Sphinx of black quartz, judge my vow. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

General questions regarding FreeBSD 10
General questions regarding FreeBSD 10: 1. Did virtualization containers (VPS) make it into FreeBSD 10? The documentation I’ve read implies that you can have nested containers, with little to no performance penalty, is this correct? How is networking handled inside these containers? 2. I'm assuming jails still exist in FreeBSD (I haven’t used BSD in a long time), how do they relate, or fit in, with VPS and Bhyve offerings? Is Xen Dom0 or KVM available on FreeBSD? 3. Can Bhyve be used with processors that don't support Extended Page Tables? For example, Xeon 5400 series processors? 4. How well does FreeBSD 10 run as a VMware vsphere , KVM, and/or Xen guest? 5: For Jails, VPS, and Bhyve, what is the footprint (i.e. memory overhead) for each implementation? 6. How stable is FreeBSD's ZFS implementation, relative to Solaris? What zpool version is in FreeBSD 10? Is LZ4 the default compression mode? 7. Is Clang and the build system setup to automatically target cpu instruction set? i.e. cc -target-cpu corei7-avx? Any performance improvements of targeted binaries? 8. Has ports management gotten any better, specifically upgrading ports? Can applications be self contained, like on the Mac, yet? Any work on rollback with ZFS? 9. I recall device support being a large hurtle for me in the past. How far behind is driver development relative to Linux, for server equipment? Has there been any community interest in porting FreeBSD (world) to Linux (kernel)? 10. How is the Java ecosystem on FreeBSD? Is LLVM specific to applications? I make the assumption that the VM in LLVM is referring to something like a JVM, for code abstraction. I haven’t used FreeBSD in ages. However, VPS, with ZFS, has me really excited; I don’t enjoy Solaris, and Enterprise Linux is still stuck in 2009, with kernel 2.6.32. I can’t find any modern linux distributions that are as reliable as I remember FreeBSD was. It’s really sad.

The documentation I’ve read implies that you can have nested containers, with little to no performance penalty, is this correct? How is networking handled inside these containers? I don't think they made it into 10. I think they are still in the projects/ tree... Last 2 posts on the topic that I've seen (Sep. 23, 2013): http://lists.freebsd.org/pipermail/freebsd-hackers/2013-September/043429.html http://lists.freebsd.org/pipermail/freebsd-hackers/2013-September/043442.html 2. I'm assuming jails still exist in FreeBSD (I haven’t used BSD in a long time), how do they relate, or fit in, with VPS and Bhyve offerings? Yes. Changed slightly -- you configure jails in /etc/jail.conf now. Jails are enhanced by VPS and Bhyve offerings (which, the best of my knowledge, require jails). [skipping questions I can't answer] 6. How stable is FreeBSD's ZFS implementation, relative to Solaris? What zpool version is in FreeBSD 10? Is LZ4 the default compression mode? At $work we're actively deploying ZFS into production. It's very stable from our testing over several years. Mileage seems to depend on configuration complexity, but overall is extremely stable. The default zpool version is 28, but if you do a zpool upgrade ... you'll then jump to the new 5000 version introduces zfs feature flags. 8. Has ports management gotten any better, specifically upgrading ports? Can applications be self contained, like on the Mac, yet? Any work on rollback with ZFS? For better ports management, you could look into poudriere. There's a tutorial on bsdnow.tv The idea is that you'll use poudriere to intelligently manage the ports you want to roll binary packages. Then on 10 with the new `pkg' framework (formerly known as PkgNg) those binary packages are intelligently applied. As for self-contained packages... I believe you want what is known as PBIs. However, I think only PC-BSD offers PBIs -- I don't think they are offered in FreeBSD 10 by default (maybe there's a way though). I assume what you mean by rollback with ZFS is... boot loader integration with BEs so you can boot to a previous snapshot. Look for that in 10.1. 9. I recall device support being a large hurtle for me in the past. How far behind is driver development relative to Linux, for server equipment? Has there been any community interest in porting FreeBSD (world) to Linux (kernel)? Driver support is improving. There's AMD KMS and many more new drivers. Knowing what kind of hardware you use would help answer the question better. We've been very happy with LSI MegaRAID/SAS support, Broadcom 10G iSCSI support, QLogic 8G FC support, and many many more. As for FreeBSD-world with Linux-kernel... that sounds like the exact opposite of the Debian kFreeBSD project (FreeBSD-kernel, Linux-world). I don't suppose there's much demand in that. People that want such a thing seem to be quite happy with ArchLinux -- which uses a BSD-style init framework. There's also ArchBSD and ArchHurd. 10. How is the Java ecosystem on FreeBSD? Well, daiblo-jdk is dead, long live OpenJDK? Seems to be the motions around here at $work. I haven’t used FreeBSD in ages. However, VPS, with ZFS, has me really excited; Even more exciting, throw in VIMAGE, Geom Multipath, NETGRAPH, and sysutils/zxfer. The possibilities are limitless as you bolt on more-and-more ^_^ I don’t enjoy Solaris, and Enterprise Linux is still stuck in 2009, with kernel 2.6.32. I can’t find any modern linux distributions that are as reliable as I remember FreeBSD was. It’s really sad. Thanks! Come on back to FreeBSD. ;) you're always welcome!
