Multiple subnets/4 subnets share the same switch/hub.

Is it alright that I connected multiple subnets like 3/4 subnets to the same
switch or hub. Eg, 192.168.100.0 255.255.255.0, 193.168.100.0
255.255.255.0, 194.168.100.0 255.255.255.0 195.168.100.0 255.255.255.0 .
Would this deprived the network performance because of multiple broadcast
domains?? Would this create one very big collision domains? Or is it
feasible??
 
It doesn't affect collision domains. They work at the hardware level. It
could have a slight effect on broadcasts.

The big difference is that traffic from one subnet to the other has to
be routed. So it has to travel the "wire" twice - once when it is sent to
the router and once when it is received from the router. If they are all in
one subnet, this is all done in one operation "on the wire", using hardware
addressing.
