compress?

victorchan

Hi all ,
I am going to compress data transmit between sever and client .
I had set "-z" on each endpoints.

But I don't know why it dosen't take any effect.
Data size number in network trace is same as before.

Is my setting wrong?

here is my config

#
# The client reads this property to create the reference to the
# "hello" object in the server.
#

Ice.Default.Locator=IcePack/Locator:default -h victorchan -p 10000 -z

Hello.Proxy=hello:tcp -p 10000 -h victorchan -z

#
# The server creates one single object adapter with the name
# "helloadapater". The following line sets the endpoints for this
# adapter
#
Hello.Endpoints=tcp -p 10000 -h victorchan -z:udp -p 10000 -h victorchan -z
#
# Warn about connection exceptions
#
Ice.Warn.Connections=1

#
# Network Tracing
#
# 0 = no network tracing
# 1 = trace connection establishment and closure
# 2 = like 1, but more detailed
# 3 = like 2, but also trace data transfer
#
Ice.Trace.Network=3

#
# Protocol Tracing
#
# 0 = no protocol tracing
# 1 = trace protocol messages
#
Ice.Trace.Protocol=0

Ice.MessageSizeMax=1024000

#
# Security Tracing
#
# 0 = no security tracing
# 1 = trace warning messages
# 2 = config file parsing warnings
#
#Ice.Trace.Security=2

#
# Glacier settings
#
Glacier.Router.Endpoints=default -p 10005 -h victorchan -z
Glacier.Router.Client.Endpoints=tcp -z:udp -h victorchan -z
Glacier.Router.Trace.Client=2
Glacier.Router.Trace.RoutingTable=1

#
# Uncomment the following lines if you want to run this demo with Glacier
#
#Ice.Default.Router=Glacier/router:default -p 10005

Can any one tell me what i need to do in order to compress all data in transmission?

The configuration seems correct. Can you post a sample of the log output? Note that short messages (< 100 bytes) are never compressed, because the compressed message would be larger than the uncompressed one.

In addition, the C# implementation will also not compress if the compressed sice would be larger than the uncompressed size. That is, the run time first looks at the message size. If that is less than 100 bytes, it doesn't not even try to compress the message and sends it uncompressed. Otherwise, it compresses the message, compares the size of the compressed and uncompressed messages, and sends whichever is smaller.

Cheers,

Michi.
