inode – How can I create disk for smaller files with good read/write speeds?

I’m trying to find the best way to store lots of small files on a volume, without hitting the inode limits. I created a new drive with:

sudo mkfs.ext4 -N 100000000 /dev/device

and this correctly shows:

/dev/device  100040704 13929894 86110810   14% /mnt/websites2

However, it seems to have made a fair hit to the speed for read/writes on that drive. I was doing some research, and came across:

How to Increase Disk Inode Number in Linux

They suggest:

sudo mkfs.ext4 -T largefile /dev/device

What is the option for “small files”? I can’t seem to find any documentation on what the values of -T can be? Also – any other suggestions on how to configure a drive for LOTS of small files (~3-10kb each), would be much appreciated!
