Yes, I understand.
When on a LAN segment you should also realize that every hardware interface to the LAN can have a different characteristic.
Some ethernet cards are more "chatty" and some are less "chatty" and some are "old" and others are "new" and some have drivers / firmware written by "A" and others have drivers / firmware written by "B".
You say "you don't have a lot of knowledge"... that's normal.
So, I am telling you what an experienced network engineer with a lot of knowledge would so.
If I had a busy LAN segment with a lot of devices on the same segment (subnet), as you have indicated, and I had two devices which I wanted to have the best communication speed between them, I would put them on their own LAN segment (subnet) and "be done with it" and maybe "retest" when the two devices are the only two devices (or three if you have a different gateway device) on that segment.

ddi_dma_nextseg
ddi_dma_nextseg(9F) Kernel Functions for Drivers ddi_dma_nextseg(9F)
NAME
ddi_dma_nextseg - get next DMA segment
SYNOPSIS
#include <sys/ddi.h>
#include <sys/sunddi.h>
int ddi_dma_nextseg(ddi_dma_win_t win, ddi_dma_seg_t seg, ddi_dma_seg_t *nseg);
INTERFACE LEVEL
This interface is obsolete. ddi_dma_nextcookie(9F) should be used instead.
PARAMETERS
win A DMA window.
seg The current DMA segment or NULL.
nseg A pointer to the next DMA segment to be filled in. If seg is NULL, a pointer to the first segment within the specified win-
dow is returned.
DESCRIPTION
ddi_dma_nextseg() gets the next DMA segment within the specified window win. If the current segment is NULL, the first DMA segment within
the window is returned.
A DMA segment is always required for a DMA window. A DMA segment is a contiguous portion of a DMA window (see ddi_dma_nextwin(9F)) which
is entirely addressable by the device for a data transfer operation.
An example where multiple DMA segments are allocated is where the system does not contain DVMA capabilities and the object may be non-con-
tiguous. In this example the object will be broken into smaller contiguous DMA segments. Another example is where the device has an upper
limit on its transfer size (for example an 8-bit address register) and has expressed this in the DMA limit structure (see
ddi_dma_lim_sparc(9S) or ddi_dma_lim_x86(9S)). In this example the object will be broken into smaller addressable DMA segments.
RETURN VALUES
ddi_dma_nextseg() returns:
DDI_SUCCESS Successfully filled in the next segment pointer.
DDI_DMA_DONE There is no next segment. The current segment is the final segment within the specified window.
DDI_DMA_STALE win does not refer to the currently active window.
CONTEXT
ddi_dma_nextseg() can be called from user or interrupt context.
EXAMPLES
For an example, see ddi_dma_segtocookie(9F).
