Hi Mark, > what benefit is there of running 64bit guests over 32bit guests if you are > only running 32 bit programs even if they do use a lot of memory?
I'd say that this kind of depends on expected usage. On a 64-bit node you can run 32-bit and 64-bit containers, so there is some flexibility. For a general purpose run-of-the-mill web- and email server which does a bit of MySQL and PHP scripting on the sidelines it usually doesn't make much difference if you use a 32-bit or a 64-bit guest OS in the container. I use the same OS in 32-bit and 64-bit versions on OpenVZ and typically see no difference in their performance. In my experience 64-bit only starts to shine when you have plenty of RAM and use applications in the guest OS which really make use of 64-bit stuff. Like massive parallel processing, heavy database usage or graphics rendering. YMMV. -- With best regards Michael Stauber _______________________________________________ Users mailing list [email protected] https://openvz.org/mailman/listinfo/users
