Need to find Bottlenecks for Maximum speed on Gigabit LAN NAS Network

[Proshooter]

I went through the forum and haven't found info to help me.
I hope maybe with some details provided you can.

I'm not a gamer, although my system is built based on components made available because of the gaming community (for which I thank them).
I use mostly Photoshop and Premiere Pro (Adobe Creative Cloud).
I move files from my network storage to my workstation,
work the files on my RAID0 drives and then move the new files back to the network.

I currently use only one of 2 LAN ports on my workstation because I haven't figured out how to configure them to recognize and utilize both in tandem to improve transfer speeds on the LAN.
When I attempt to create a Bridge with 2 5e cables running to the switch I get the following message:
"To create a Network Bridge, you must select at least two LAN or High-Speed Internet connections that are not being used by Internet Connection Sharing" ???

I would like to move large files to and from the network faster if possible.
I will typically drag a whole folder of files to my local drive (mix of large and small files).
Currently files transfer as low as 5MB/s but sometimes as fast as 25MB/s from the network.
My goal is closer to 100MB/s.
What can I do to achieve this?

My current setup;
> 2 - Drobo FS units each with 5 drives - 7200RPM 6Gb/s
one with 4TB drives, the other with 2TB drives (30TB total)
setup as RAID5 for each with 14.5 & 7.2 usable space (21.7TB)
(I plan to add a new Drobo5N with 4TB drives down the road)
I prefer Drobo because of the 4 brands of NAS I've used over the years this is the most dependable to avoid data loss.

Thank you for your insight and suggestions

You can not use both ports without a special switch that supports 803.ad link aggregation. It still will not accomplish what you want even if you were to buy a switch. It does not load balance by packet it load balances by session at the very best so it does increase the speed for a single file transfer.
Do not even worry about jumbo frames until you manage to get the speeds above 600 or 700mbit. You traffic should only pass though your switch and it is pretty much transparent and does not delay the data.
Cat5e will run to 1g without any issues.

You delay likely is in the machines and not the network. Since I am a network guy you get near the limit of my knowledge when you talk about delays related to network connected hard drives. If you have a second pc I would try some of the lan performance testing tools. I normally use a very old one called IPERF that is completely run from memory. This generally tests just the network part and is not affected by things like memory or disk latencies.

I have no trouble copying files at close to 400mbit/sec between 2 PC and one is a old winxp box with slow hard drives.
