Had a walk through cambridge today and found first and only raspberry pi shop.
Bought a pi4, 4gb. Installed scratch3, network is nice and fast here in hotel.
Did a few performance tests (using VNC connection), using scratch3 and scatch1.4
- for two sprites, rotate 1 degree, for 10 sec. scratch 3: 303 rotations, scratch 1: 460 (larger is better)
- for two sprites, place to opposite corners. Let them move one step
towards the other till reaching the other corner. They meet in the middle and continue till other corner.
scratch 3: 13.2 sec, scratch 1: 8.7 sec (smaller is better)
- the pingpong game: one sprite sends ping, when the other receives ping it
sends pong which the first one responds to again with -guess- ping.
scratch3 302000 in 10 secs, this varies a bit. scratch1 231 in 10 secs. This was
similiar to scratch2. Event performance is snail-like in scratch1.
These results are similiar to those in scratch2.
