Speed decrease from BOINC 4.09 -> 4.45?

Has anyone noticed a speed decrease (takes more time to complete a wu) using v4.45?.. maybe its just the WUs im getting, but the last 3 or 4 have taken a little over 3hours compared to 2h 30mins it takes on 4.09.. i only upgraded this afternoon, and am wondering if maybe theres an 'unoptimization' or something

cheers,

Boinc version shouldnt make impact on chrunching times, Its most likely work units with low AR that take longer to complete. Also look if some other program uses CPU cycles.

hmm thanks for the reply, you were right, i just crunched a unit then in 'normal' time.. mustve just been some bigger units i had before on a sidenote: gah, so hard to keep in the top 100people with only one pc >_> must get my new pc soon lol
