Hi Doug,

i've moved to MMLEM.OS2 AN driver (1.1.3), but i'm still

seeing poor

datarates 4,7-6MegaBytes/sec  laptop -> AOS 503 VM
(the VM is hosted on a intel xeon 8 cores supermicro server)


massimo

more tests:
virtual-nic: AMD 1core 2,5MB/sec
virtual-nic: AMD 2core 3,5MB/sec
virtual-nic: MML 2core 4,5MB/sec
with MMLEM is syrely better
but very far for a VM that has his storage on SSD
and connected with Intel Gigabit NICs
any help?

Well, the AMD device is 100 Mbs, while the Intel device is 1000
Mbs, so you can't compare them. Since NICs work at a limited
speed (very much slower than any modern disk drive, even at

1000

Mbs), I don't know why you are seeing those numbers. My guess

is

that you do not have a good setup.

we have see allmost all parameters...

It would be easy to miss something.

You also need to remember to
mark virtual disk drives as being SSD, in the VM, or VBox will
insert seek delays. It doesn't matter what the real disk is.

already set SSD on all VMs
moving a 6GB file from a partition to another (all JFS)
inside the same guest VM i get >100MegaBytes/sec (also

120MB/sec)

so it's not a disk datarate issue

thanks

i've tried an old eCS2.2b guest on VMware hypervisor ESX 6.5

running on

the same hardware

i get about 20MegaBytes/sec ftp datarates...
same eCS 2.2b on vbox i get 4,5MegaBytes/sec ftp datarates...

(not talking that with Vbox i can't autostart VMs at boot)

There is a way, but I don't remember how. I am sure it is in the

docs

somewhere.

there is a way under linux as host
i'm running WS2019 with i'm much more comfortable

anyway i've found a way to start the 2 VMs at Win logon
which is sufficient for me at the moment

there is also a software that runs VMs as services
but it cost 49$

https://www.coretechnologies.com/products/AlwaysUp/Install.html

i've already bought the software that do live bkups...
anyway i will mind if buy it

there is also this software:

https://github.com/onlyfang/VBoxVmService

that's free, but it has issues (it don't work at all, sigh)

I don't know anything about any of them. I use VMs to be able to run
various versions of software, so I can try things, when something
isn't working. At the moment, I don't have a good setup to try
running a FTP server, so I can't try that without doing another
install.

if i find a free sw for live bkups of VMs under ESX
i will go with ESX has hypervisor

>From the little that I know about ESX, it does not virtualize a

machine. It shares a real machine with more than one operating
system. If it works, use it.

i still have to find how to schedule bkups
how to add notifications

i've found "GhettoVCB"* that's free runs under ESX free

hypervisor

and do live bkups (i mean bkups without turning off the VMs)
but i still have to find a way to schedule it
e.g. one time per night...

I never bothered under windows, although the Task Scheduler
should run a program, at a scheduled time. Most operating systems
have some sort of Cron program.

and it uses NFS as protocol that i don't like so much
anyway i also have a Qnap nap that use NFS
so i could use it as storage for bkups...

I don't use windows enough to worry about nightly backups.

I use
RSync under OS/2 (using the DragText scheduler). There is
DeltaCopy, that runs RSync under windows. I don't know if it would
do what you want.

I still think you have a bad setup in VBox, but I don't have the

time

to try to figure it out.

the CPU is a xeon 8cores but clocked at 2Ghz, i guess that Vbox

is very

"clock/frequency" oriented, the much higher is the clock, the faster

are

performances

There are a lot of pieces that fit together, to improve performance.
A fast host definitely helps, but that isn't the only thing.

this is my tought at the moment
as far from my tests, MS free Hyper-V is way the faster

hypervisor

around
but unfortunately eCS/AOS don't run under it :(
this one does everything, live bkups, live replica and
comes with a number of interesting features

AFAIK, Hyper-V only works with windows guests.

there was a post, some time ago, in this mail
list, about how to make a modern VBox setup for OS/2

(probably

eCS at the time)

i'm subscribed since 3th jan 2020 :(

Web archives are publicly available at: http://lists.2rosenthals.com,
but it seems that a lot of content went missing, when the Arca Noae
servers crashed. I keep them for one year, then delete them. What
you need would be somewhere in the middle of the missing stuff.

I guess I need to do the setup thing all over again, when I find the
time.
