Re: Expected haproxy performance inside a VMWare instance

I know Patrick,

I finish my email with " but it's not a very big setup. "

I just wanted to talk about my vm experience. Also RDP traffic is not very similar to http either

For your information, on those server In a vm

• I send 95Mb of data using 1 ftp session on a 100Mb link network and not using much CPU on the guest and on the HOST that vm use ~ 17 % off 1 Core

On the host server I add 99 Mb transfer and ftp server was not using more than 0,5 % CPU ( in the HOST )

Just for the record, on those host Dell 2950 in RAID 5 with four (4) 15K RPM SAS disk with can write 350 MB of data using 1 rsync transfert.

Also remember that I'M using vmware server free version product on top of centos 5 64 bit

Voilà
