µCLinux - How to minimize buffers

Hello, I guess it wasn't the buffers that consumed all my memory after all. When I use the command:

cat meminfo

I get the following result:

# cat meminfo
MemTotal:         1220 kB
MemFree:           380 kB
Buffers:           148 kB
Cached:             56 kB
SwapCached:          0 kB
Active:            136 kB
Inactive:           60 kB
HighTotal:           0 kB
HighFree:            0 kB
LowTotal:         1220 kB
LowFree:           380 kB
SwapTotal:           0 kB
SwapFree:            0 kB
Dirty:               0 kB
Writeback:           0 kB
Mapped:              0 kB
Slab:              512 kB
Committed_AS:        0 kB
PageTables:          0 kB
VmallocTotal:  4194303 kB
VmallocUsed:         0 kB
VmallocChunk:  4194303 kB

It seems that it is the Slab allocator that eats most of my memory, but how can I minimize its consumption? And what exactly DOES this Slab-allocator actually do?

Hope anybody can help me.

By the way I removed the RAM-drive in the kernel-setup - so now i write:

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

mount -t ramfs ramfs /var -n[/b]

--- Quote End ---

instead of:

<div class='quotetop'>QUOTE </div>

--- Quote Start ---

mount -t ext2 /dev/ram0 /var -n[/b]

--- Quote End ---
