Hello,
I am using the following code to create the chain of two files:
Int_t fnum1 = chain->Add(FilesToRead1); Int_t fnum2 = chain->Add(FilesToRead2); int nb_read = chain->GetEntry(0);
But I have faced with the following problem. When I do a cycle over all entries (250+250 in my case) the program works fast just for 250 entries from the first file. Starting from the second (Event number 251), it seems to load to the memory entry by entry and execution becomes much slower.
How to speed up the execution ? Perhaps one needs to load a larger portion of entries (may be equal to the number of entries in each file)?
thanks,
Dmitry
