Vitesse théorique et constatée d'un switch

"HD" <hd@anti.spam.fr> a écrit dans le message de

Bonjour,

Nous avons depuis peu un switch HP ProCurve 2824. J'ai configuré les ports
en "Auto-100" car il est peu probable que nos câbles RJ45 puissent
atteindre le Gigabit/s...

Lors des transferts de fichiers pendant la nuit je constate que la vitesse
atteinte est de 3 Mo / sec avec le serveur et le poste destinataire tout
deux en 100 Full Duplex. La vitesse théorique pour du 100 Mb/sec est de
12,5Mo/sec. Je sais que cette vitesse n'est que théorique... Mais que
pensez

vous de mes résultats ? Est-ce cohérent ? Avez vous une astuce pour
améliorer ces performances ?

Je précise que pendant la nuit toutes les autres machines sont éteintes...

Merci d'avance pour votre aide.

c'est quoi "auto-100" ?
si c'est automatique, il n'y a pas 10,100,1000...

mais de façon générale, cherches plutot du coté de ton serveur et de ta
station.
le switch n'a rien à voir la dedans.

bon courage

si tu forces, tu forces des 2 côtés.
le switch en 100/auto, tu as forcé la vitesse à 100 et le duplex se
négocie.
les pc en 100/full, tu as forcé les 2.
dans ce cas tu as un conflit sur le duplex

Salut,

Lors des transferts de fichiers pendant la nuit je constate que la vitesse
atteinte est de 3 Mo / sec avec le serveur et le poste destinataire tout
deux en 100 Full Duplex. La vitesse théorique pour du 100 Mb/sec est de
12,5Mo/sec. Je sais que cette vitesse n'est que théorique...

Tu te trompes. C'est la vraie vitesse réelle et observable des bits qui
passent sur le câble, elle n'a donc rien de théorique.

Mais que pensez
vous de mes résultats ? Est-ce cohérent ? Avez vous une astuce pour
améliorer ces performances ?

Je pense que si tu veux mesurer un débit ethernet, faire des
lectures/écritures de disques n'est pas ce qu'il y a de plus cohérent.

Je suis du même avis.
Cela devrait d'ailleurs être facile à vérifier en constatant que
l'utilisation d'un cable croisé pour relier les deux machines concernées
n'améliore pas les performances....

D'ailleurs avec un tel nom/pseudo je suis étonné que la piste n'ai pas coulé
de source ;-))

autre suggestion avec l'hypothèse de machines windows: booter sur un cd
linux live et mettre en place un serveur ftp ou samba et faire le ^test des
vitesse atteintes....

bonne chance.

Roast Child with Cornbread Stuffing

Turkey may be substituted for this classic holiday feast.
Although time consuming, this dish seems to take longer than it actually does;
as the entire house is filled with such a heavenly aroma,
the waiting becomes almost unbearable.

1 whole child, cleaned and de-headed
1 batch cornbread stuffing (see index)
½ cup melted butter

Remove the giblets from the infant and set aside.
Stuff the cavity where the child?s genitals and anus were located
using ½ cup per pound of meat.
Tie the arms flat to the body, then pull the skin flaps up to close the cavity.
Now tie the thighs up tight to hold it all together.
Place breast side up in a large metal roasting pan.
Bake in 325° oven covered for 2 hours.
Remove cover, stick a cooking thermometer deep into one of the
baby?s buttocks and cook uncovered till thermometer reads 190°,
about another hour.



Pro-Choice Po-Boy

Soft-shelled crabs serve just as well in this classic southern delicacy.
The sandwich originated in New Orleans, where an abundance of abortion clinics
thrive and hot French bread is always available.

2 cleaned fetuses, head on
2 eggs
1 tablespoon yellow mustard
1 cup seasoned flour
oil enough for deep frying
1 loaf French bread
Lettuce
tomatoes
mayonnaise, etc.

etc
Olive oil
breadcrumbs
Tomato Gravy (see index)

Boil the cabbage leaves for 2 minutes to soften.
In skillet, brown the meat in a little olive oil,
then add onions, peppers, and celery (all chopped finely)
and season well.
Place in a large bowl and cool.
Add seasoned breadcrumbs and a little of the tomato gravy,
enough to make the mixture pliable.
Divide the stuffing among the cabbage leaves then roll.
Place seam down in a baking pan.
Ladle tomato gravy on top,
and bake at 325° for 30 - 45 minutes.



Umbilical Cordon Bleu

Nothing is so beautiful as the bond between mother and child,
so why not consume it?
Children or chicken breasts will work wonderfully also.

4 whole umbilical chords (or baby breasts, or chicken breasts)
4 thin slices of smoked ham, and Gruyere cheese
Flour
eggwash (milk and eggs)
seasoned bread crumbs
1 onion
minced
salt
pepper
butter
olive oil

Pound the breasts flat (parboil first if using umbilical
cords so they won?t be tough).
Place a slice of ham and cheese on each, along with some minced onion
then fold in half, trimming neatly.
Dredge in flour, eggwash, then seasoned

so easy to
procure if such a lucky find is at hand (just pick him up from the crib and
he?s good to go)!

SIDS victim, cleaned
½ cup cooking oil
Carrots
onions
broccoli
whole cabbage
fresh green beans
potato
turnip
celery
tomato
½ stick butter
1 cup cooked pasta (macaroni, shells, etc.)

Remove as much meat as possible, cube, and brown in hot oil.
Add a little water, season, then add the carcass.
Simmer for half an hour keeping the stock thick.
Remove the carcass and add the vegetables slowly to the stock,
so that it remains boiling the whole time.
Cover the pot and simmer till vegetables are tender
(2 hours approximately).
Continue seasoning to taste.
Before serving, add butter and pasta,
serve piping with hot bread and butter.



Offspring Rolls

Similar to Vietnamese style fried rolls, they have lots of meat
(of course this can consist of chicken, beef, pork, or shrimp).
Who can resist this classic appetizer; or light lunch served with
a fresh salad? Versatility is probably this recipe?s greatest virtue,
as one can use the best part of a prime, rare, yearling, or the
morticians occasional horror: a small miracle stopped short by a
drunk driver, or the innocent victim of a drive-by shooting...

2 cups finely chopped very young human flesh
1 cup shredded cabbage
1 cup bean sprouts
5 sprigs green onion, finely chopped
5 cloves minced garlic
4-6 ounces bamboo shoots
Sherry
chicken broth
oil for deep frying (1 gallon)
Salt
pepper
soy & teriyaki
minced ginger, etc.
1 tablespoon cornstarch dissolved in a little cold water
1 egg beaten

Make the stuffing:
Marinate the flesh in a mixture of soy and teriyaki sauces
then stir fry in hot oil for till brown - about 1 minute, remove.
Stir-fry the vegetables.
Put the meat back into the wok and adjust the seasoning.
De-glaze with sherry, cooking off the alcohol.
Add broth (optional) cook a few more minutes.
A

use high quality beef or pork roasts (it is cheaper and better to
cut up a whole roast than to buy stew meat).

1 stillbirth, de-boned and cubed
¼ cup vegetable oil
2 large onions
bell pepper
celery
garlic
½ cup red wine
3 Irish potatoes
2 large carrots

This is a simple classic stew that makes natural gravy,
thus it does not have to be thickened.
Brown the meat quickly in very hot oil, remove and set aside.
Brown the onions, celery, pepper and garlic.
De-glaze with wine, return meat to the pan and season well.
Stew on low fire adding small amounts of water and
seasoning as necessary.
After at least half an hour, add the carrots and potatoes,
and simmer till root vegetables break with a fork.
Cook a fresh pot of long grained white rice.



Pre-mie Pot Pie

When working with prematurely delivered newborns (or chicken) use sherry;
red wine with beef (buy steak or roast, do not pre-boil).

Pie crust (see index)
Whole fresh pre-mie; eviscerated, head, hands and feet removed
Onions, bell pepper, celery
½ cup wine
Root vegetables of choice (turnips, carrots, potatoes, etc) cubed

Make a crust from scratch - or go shamefully to the frozen food section
of your favorite grocery and select 2 high quality pie crusts (you
will need one for the top also).
Boil the prepared delicacy until the meat starts to come off the bones.
Remove, de-bone and cube; continue to reduce the broth.
Brown the onions, peppers and celery.
Add the meat then season, continue browning.
De-glaze w

meat, vegetables, and
fruit such as pineapples or cherries on the skewers.
Don?t be afraid to use a variety of meats.
Grill to medium rare,
serve with garlic cous-cous and sautéed asparagus.
Coffee and sherbet for desert then walnuts, cheese, and port.
Cigars for the gentlemen (and ladies if they so desire)!



Crock-Pot Crack Baby

When the quivering, hopelessly addicted crack baby succumbs to death,
get him immediately butchered and into the crock-pot, so that any
remaining toxins will not be fatal. But don?t cook it too long,
because like Blowfish, there is a perfect medium between the poisonous
and the stimulating. Though it may not have the same effect on your
guests, a whole chicken cooked in this fashion is also mighty tasty.

1 newborn - cocaine addicted, freshly expired, cleaned and butchered
Carrots
onions
leeks
celery
bell pepper
potatoes
Salt
pepper
garlic, etc
4 cups water

Cut the meat into natural pieces and brown very well in olive oil,
remove, then brown half of the onions, the bell pepper, and celery.
When brown, mix everything into the crock-pot, and in 6 to 8 hours you
have turned a hopeless tragedy into a heartwarming meal!
