Windows xp x64 /Total Commander 7.04a copy routine on USB 3

Windows xp x64 /Total Commander 7.04a copy routine on USB 3.0 usb flash stick.

How to setup TC copy options to get the real writing speed on USB stick, because I know that reading speed of my stick is 55Mb/s and writing speed is 11Mb/s.
But the tc will show firstly the value of copy speed from the source to the virtual cache memory till the available memory is up or available for cache usage, than after the cache is full, TC would show crawling speed of 400kb/s to compensate the fact that its not at the right actual position at the writing point on the destination which is the USB stick.

For example I used 16GB stick and I copied 15.5GB file on the ntfs formatted stick.
The writing speed will jump to 128MB/s till it fill out the 6.7GB which is the free size of cache in memory (on system with 8GB of ram), when the copy routine fills out the cache, the writing speed will crawl to 400kb/s and it will stay at 400kb/s till it compensate.
Then after some time it will again use the memory cache cache and the speed will jump to 128MB/s which is the reading speed of my WD-HDD and it will top out the memory cache after the new 6.7GB and it will drop to 400kb/s till the end of copy.

The only partial solution is to set "also use big file copy mode (not using cache) and setting source +target on different disk" to value other than default like 256, 512, 1024k ...
Its not safe way of copying and its not at exact writing speed its slower for 10-15% but it will show the exact speed with exact estimated time.

I understand that the writing speed is ok with every copy method you set but the calculation is screwed.
Seems its some incompatibility with TC-winxp64bit-USB sticks

OK, just to report my latest findings, seems that setting compatibility mode off and setting 2048k for "also use big file copy mode (not using cache) and setting source +target on different disk" is giving almost maximal writing speed and TC is able to calculate the speed.
