In blockchain directory, much more files will be created. Any other disadvantage? BTW I running Bitcoin core with 100 Mb cache on winXP 32bit with 1GB total system memory and it runs fine

- but I dont have other programs open when Bitcoin core is running because it would start swapping the memory to hdd
For me, it need long time to synchronize with the network, bro. How about?.
It takes me about half hour for every full day I have to synchronize, not much problem when I open the wallet daily.
