We're using Debian kernel 2.6.18-fza-028stab053.5-686
When we compare local disk write performance between HN and VE, we can notice 40% performance less in the last case.
Test :
//from HN
# time yes "Bonjour ici les bidibules"> /var/lib/vz/private/105/tmp
gives 4 472 987 lines/seconds
// from VE
# vzctl enter 105
# time yes "Bonjour ici les bidibules"> /tmp
gives 2 656 845 lines/seconds
Inside the same VE NFS write performance is better than local disk access (3 648 706 lines/s) !!
An idea ?
