tcp/ip fast input-output on kHz frequencies - is it possible?

Hi! Ive got a task to read data from virtual tcp/ip server with matlab, and ive got some problems - with simple code matlab is too slow. Here is it:

obj1 = instrfind('Type', 'tcpip', 'RemoteHost', '127.0.0.1', 'RemotePort', 2541, 'Tag', '');

fopen(obj1);

tic

for i=1:1:10

output_data = query(obj1,'11');

toc

end

fclose(obj1);

matlab is too slow with every operation of input-output - it takes about 0.25 sec, that is only 4 Hz. Is it possible to do the same thing, but much faster - on frequencies about kHz or more?
