It is indeed way more efficient to save big files as demonstrated by this example model:

model CONCAT

global{
	
	int nb_concat <- 10000;
	
	float seed <- 3.14;
	string f <- "file.txt";
	
	init {
		save "" to:f rewrite:true;	
	}
	
	reflex eval {		
		do save_directly;
		do optimized_save_directly;
		do concat_first;
		do concat_ope;
		do save_list;
	}
	
	action concat_first{
		benchmark message:"\nconcat string" repeat:10 {
			string s <- "";
			loop i from:0 to:nb_concat{
				s <- s + "" + rnd(0, 9);
			}
			save s to:f format:"txt";
		}
	}
	
	action save_directly {
		benchmark message:"\nsave directly" repeat:10 {
			loop i from:0 to:nb_concat{
				save "" + rnd(0, 9) to:f rewrite:false format:"txt";
			}
		}
	}
	
	action optimized_save_directly {
		benchmark message:"\noptimized save directly" repeat:10 {
			loop i from:0 to:nb_concat{
				save "" + rnd(0, 9) to:f rewrite:false format:"txt" buffering:"per_simulation";
			}
		}
	}
	
	action save_list{
		benchmark message:"\nsave list" repeat:10 {
			list<string> l;
			loop i from:0 to:nb_concat{
				l <+  "" + rnd(0, 9);
			}
			loop i over:l{
				save i to:f format:"txt" buffering:"per_simulation";				
			}
		}
	}
	
	action concat_ope {
		benchmark message:"\nconcatenate operator" repeat:10 {
			list<string> l;
			loop i from:0 to:nb_concat{
				l <+  "" + rnd(0, 9);
			}
			save concatenate(l) to:f format:"txt";
		}
	}
}
