search for: vmclient

So I have an entry for a USB device ( ID 051d:0002, UPS) I want to use with a given vm client. In that vm client's config file I added something like this: <hostdev mode='subsystem' type='usb' managed='yes'> <source> <vendor id='0x051d'/> <product id='0x0002'/> </source> </hostdev>

...: $ iostat -kx /dev/sda 5 1000 On my own workstation with a single sata drive, I get about 54 MB/s. On the hosts having the RAID5 disks, and without any vmware client running, I get about 20MB/s. As said, not really fast, but it should be good enough for our purpose. However when I start one vmclient and repeat the test, the write speed drops to half to about 10MB/s. With 2 clients the write speed drops even more to about 5 MB/s. With 3 clients only 2 MB/s, and with 4 MB/s I get only 0.5-1 MB/s write speed. The iostat shows the disk is 100% utilized, and the processor is spending most of it...
