comment ext4 production ready on kernel 2.6.32 (debian6)?
By backports I meant porting linux kernel features from recent kernels back to 2.6.32 without breaking API/ABI e.g. new versions of drivers or sometimes new features.

It's worth mentioning that RedHat 2.6.32 has a bunch of redhat-specific backports from recent kernels, so it can not be compared to Debian's.

comment Should I set rto_min for a route inside data center?
@Janning max latency is proportional to cumulative size of all buffers along the way. Speed of light is negligible in your case.

comment Should I set rto_min for a route inside data center?
I guess rto_min should be set not with regard to current latency, but w.r.t. sizes of buffers along the way and bandwidth. For example in presence of traffic bursts switch/router can hold frame/packet for couple of milliseconds.
