SYS E3 server vs E5 server (i/o benchmark)
I have an weird issue when i benchmark my 2 server on SYS.
E3 currently server runs few websites.
E5 currently doesn't run any websites. Just installed.
Both have thick provision.
This is old server of mine running on VMware Esxi VM

And this is the new server i'm planning to move running on VMware Esxi VM.
CPU model : Intel(R) Xeon(R) CPU E5-1650 0 @ 3.20GHz
Number of cores : 12
CPU frequency : 3199.999 MHz
Total amount of ram : 64261 MB
Total amount of swap : 16383 MB
System uptime : 55 min,

Any ideas about why it gets that low I/O speed?

Any magician here? So he can say what drive he using, raid etc etc.
This is not benchmark, this is asking for help without provide anything usable to debug the issue
tommy is right. the answer is (with regard to the provided information): it is the amount of swap space which is causing the issue. Halve the amount of swap in second server to double I/O speed :-o
to be constructive: post output of dmesg, /proc/mdstat, ps, iostat etc etc.
