[zeromq-dev] Windows 7 problem - error in zmq_msg_init_size: Not enough space

Hi Andy,

The throughput program (perf/remote_thr.cpp) uses a PUSH socket with
default high-water mark, meaning they'll queue 1,000 messages before
blocking on send. If you ask for 8MB messages, that's 8GB of memory it
will try to allocate. If you want to use larger messages, you can make
your version of this program and set the high-water mark to something
lower (100). If there was no HWM, it would try to create and queue
10,000 messages (80GB).

Hope this helps
Pieter
