Similar systems - different communication speed
Two companies have a dedicated T1 between their offices,
at company A there is one OSR 5.0.7 system (A1),
at company B there are two OSR 5.0.7 (B1 and B2) and one OSR 5.0.6 (B3).
The A1, B1 and B2 are the same HP ML380s, the B3 is older HP h/w
There is a ftp-based data exchange established between system at A and all three systems at B.
The speed between A1 / B1 and A1 / B2 is around 55 Kbytes/s; the speed between A1 and B3 is around 220 Kbytes/s.
The routing scheme at company B is the same on all three boxes. The B2 and B3 are on the same subnet, B1 is on another subnet. The load on B3 is actually the highest of those three at company B.
I can't understand how is the older and fully loaded system achieves 3 times higher speed.
What should I check and tweak to ensure all three systems from B would get the same 200+ Kbytes/s speed?
