Original Issue

During Use the program constantly pauses not letting me interact with the window at all. Windows even gives it that lovely not responding overlay. This happens about every 3 seconds and lasts for about 3 seconds. During the normal 3 seconds it uses normal amounts of memory and CPU(~7%) but during the dead phase it spikes CPU usage(~19%).

I was running version 1.99 when this started to happen since then I've updated to 2.28 and still get the issue.
I run Win7 64 bit.
Tried a compete shut down and restart.
While not seeding or downloading The application runs smoothly.
Attached is a link to a print screen of what the cycle looks like:

Discovered AVG as culprit

Checked resource monitor and noticed AVG was pushing out 500+ hard faults in memory as soon as Tixati was active.
Disabled AVG and let Tixati run for a solid 10 mins. No problem at all...
Tested again by enabling AVG and sure enough that's the issue.
Added an exception for Tixati in AVG and it still has an issue with it.

The only Work around I've found for this at the moment is to totally disable AVG while running Tixati.

I 100% pin this issue on AVG but find it very unlikely that they will change/fix this on their end, and would love to see if any changes are possible to fix the issue. If not, I think it's time to find a new Anti Virus.

I would report this to AVG as well. While Tixati may at this point not have the market share of the heavyweight bittorrent clients, it has its public and it's growing, and it's in AVG's best interest to keep market compatibility to a maximum, and your testing with adding an exception for Tixati to AVG and AVG still misbehaving, clearly suggests that the problem resides in the latter.

As a side note, personally I don't use real-time antivirus protection and I'm adamantly against it exactly because of this kind of thing (nothing to do with Tixati in particular or even bittorrenting in general, but with everyday's computer usage since in my experience resident antivirus solutions ALWAYS cause trouble with something or other while at the same time slowing down your PC and consuming vital system resources). Plenty of good antivirus products around which work just fine as on-demand scanners, with no need to forcibly enable real-time stuff. But I realize that this comes with experience and that a user's needs may vary.

What versions of AVG? On Demand scanning?
I had an issue with both ESET and Windows Defender until I made rules for both tixati.exe, the data folders, and my temp download folder
