There are performance differences between send and receive that are
implementation-dependent (i.e, they change from operating system to
operating system). They are insignificant at recommended argument sizes
(say, 64K) but become large with these extraordinarily large argument
arrays.

This is the sort of thing that lies behind the exhortation not to use
marshaling to pass large buffers. The suggested architecture involves
using COM to exchange control information, and then to use some other
mechanism (WinInet? Shared files?) to pass data.

Subject: Proxy to Stub and stub to proxy

I have a exe com component which run in a remote computer and my client
is
in another computer.
When i try to do a put data, transfer a 30 mb data from the client to
the
exe component, it takes a lot of time(i.e i tranfer the data from proxy
to
stub or the component), it takes around 20 minutes.But when i do a get
data
from the component to the client application, it takes a much less
time(around 4 minutes), here the data transfer is from the component to
the
client application(i.e stub to proxy or the client app).Why is the huge
difference.Both machine are win2k advance servers.

What is the reason for the delay, though it is the same data transfer.Is
stub to proxy faster than the proxy to stub in remote computer
scenarios.

Thanks
Pradhan
