However if vmplayer access a partition or harddisk it is not cached by the host OS's file system. That might make it even slower. Unless of course the database is in particular on a raw device that is directly accessed from the guest OS, as Sandy pointed out. The caching doesn't make a difference, as it is not really different. The question itself is not relevant. Fact is that performance will increase a lot if you use a raw device.
Well, then that software is written poorly. For example, the kernel can use
Agreed! We even opened a call by VMWare to debug the problem but they weren't very interested, so we had to use what we got, a bit frustrated and one illusion poorer.
a file or a partition/disk for swap. Both are virtually the same speed. There's few reasons accessing physical storage through a file would be any slower that accessing it through a block device. (The most noticable would be severe fragmentation, but modern filesystems don't suffer from that often.)
True, previously swap was recommended to be installed on its own partition, now it doesn't make much difference. Unfortunately, it seems as if priorities are a bit different as far as VMWare is concerned. This goes for the enterprise version (VMWare Infrastructure) as well as for the cheap versions. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
