Windows 7: MS Security Essentials slows down file transfer/PC?

MS Security Essentials slows down file transfer/PC?

I've been using MS SE Beta since it came out on W7 x64 7100 Ultimate RC and few days ago I installed W7 7600 x64 Pro RTM and also updated MS SE to 1.0.1500.0 and I'm 100% sure that MS SE Essentials slows down my PC, especially while copying/transferring files/folders between partitions/over the network (PC1 to PC2 etc).

I tested transferring many time with MS ES on/off and I can say for sure MS slows down file transfer significantly, e.g.

8GB between PC1 and PC2 and also 8GB from partition A to partition B

With MS ES ON = 8 mins
With MS ES OFF = 4/5 mins
With MS SE OFF and AntiVir ON = 4/5 mins

I really like the idea of having MS providing Firewall/AntiVirus/AntiMalware/built in CD/DVD burner program etc cause I strongly believe it would be less potential conflicts to the OS.

I no longer need Nero and 3rd party Firewall after testing out Windows 7 built in Firewall and CD/DVD burner program, MS did an excellent job here.

I know MS SE is still very new, and I would rather not use the good old AntiVir, however the slowdown of transferring files bother me, cause I do a lot of transferring between my partitions/PCs (12 TB).

Any suggestions? or should I disabled the "Monitor file and program activity on your computer" under Settings - Real Time Protection?

Thanks in advance.

Not so much a suggestion, but it may be that MS has debug code built into the beta. I noticed a big increase in the speed of Win7 when I went from RC to RTM. I think they take out a lot of stuff to help them diagnose and probably report back to them. Maybe it will be the same with MSE.

File Transfer speed slows down over time.
Is this normal? Over a long period of time, my file transfer/copying speed slows down. For example, at the beginning it's 80-90 mb/s. Then like 5-10 mins later it goes to 30 mb/s or lower. I notice this for big files, not so much with smaller files. I tried with my internal hard drive and the...
