my application gets slower while using remote tools

hi all
Currently i am using the ver6.12.03 BSP for EVM_3530 board for BeagleBoard(C3). issue is when i execute an application for calculating the time taken for read/write operation to MMC card with the remote tools open the application becomes very slow. However it is fast enough without remote tools open.
i am unable to undertsand the dependency of the remote tools with the BSP. The similar behavior is also seen while running any other application also.
Please suggest me what can be the reason and solution for the same.
