Slow performance over screen sharing

[Tech198]

When using built in Finder side bar to access Mac Mini from my other Mac, i encounter slow performance to the point, best describes it as, i can see the Mac HD disk window opening up from small to window size when u double click, menu scrolling is slow as well

I started seeing this when i started doing random pass-disk erases on two external drive via Terminal,, and saw a spike in Activity Monitor: (attached) under the process.

However the issue is only slow over wifi,,, when i connect to Mac mini via LAN, everything is ok.

I am sitting right next to N router and while i have Apple on Wifi network as well, it doesn't have any problems. Mac mini is connected to router via Cat 6 cable.

Could it be just resolution? if i move mouse, its fast as ever even over Wifi,, its just the windows/menus transiting which is slow.

Solution solved,,, it was due to me running two Terminal sessions at once,,, Coupled with the fact the Mac mini only has 4 Gig, and going over screen share it probably asking too much..

Resorted back to just one Terminal session, and everything back to normal.
