If I increase the size of sstables, performance will be perfect, please anyone can list me all key parameters i want to edit it to increase performance of cassandra. i think exists a lot off parameters want to change it.

I tried to edit cassandra-env.sh to increase number of cores and heap size

system_memory_in_mb="50000"
system_cpu_cores="16"

I don't have any errors, but I have a large latency in write.

I want to know what's the main parameters I can edit to have best performance

In Cassandra many things need to tune to get high performance based on application behaviour and nature. you can tune JVM parameters upto a certain limit and can get better performance for highly write intensive application. Also,you can select or change compaction strategy.
