when i run position measurement vi using 6602 & continuous handshake input vi using 6534, counter vi updates the counter value slowly

[Nirmal_Sharma]

Hello,
I am using buffered continuous handshake input vi to acquire the digital data using PXI-6534. I am also running the position measurement vi to acquire the rotary encoder motion using PXI-6602. When i run both above vi one after one they work fine. But when i run both the vi together (i m opening both the vi in separate windows, then i run individually at same time), position measurement vi updates counter value slowly (though the pulses coming to 6602 counter are at same rate of 3.6 KHz). I m mentioning the system resources spec:
PXI-1002 using MXI-3 link(5 m copper wire)
Host PC: Intel Pentium 4 (2.6 GHz) with 256 MB
RAM.

I am attaching both the vi. Position measurement vi is same but cont handshake input vi is taken from example programms).

Pl. help urgently with some solution.

Thanx in advance,

Best Regards,
Nirmal Sharma
