What is the enough SDRAM capacity for uClinux

Genenally speaking, What is the enough SDRAM capacity for a uClinux kernel with net supported? 


Here is some logs about memery. 

PID hash table entries: 128 (order: 7, 2048 bytes) Dentry cache hash table entries: 4096 (order: 2, 16384 bytes) Inode-cache hash table entries: 2048 (order: 1, 8192 bytes) Memory available: 14592k/16384k RAM, 0k/0k ROM (1427k kernel code, 189k data) Mount-cache hash table entries: 512 (order: 0, 4096 bytes) cat /proc/meminfo MemTotal:        14656 kB MemFree:          7576 kB Buffers:          1592 kB Cached:           1080 kB SwapCached:          0 kB Active:           1532 kB Inactive:         1140 kB HighTotal:           0 kB HighFree:            0 kB LowTotal:        14656 kB LowFree:          7576 kB SwapTotal:           0 kB SwapFree:            0 kB Dirty:               0 kB Writeback:           0 kB Mapped:              0 kB Slab:             4160 kB CommitLimit:      7328 kB Committed_AS:        0 kB PageTables:          0 kB VmallocTotal:        0 kB VmallocUsed:         0 kB 


1. could you help me to figue out what are they really tells us? 

2. which memory is managed by kernel?  

3. What is the Slab?  

4. Except for MemFree, which Memery group in meminfo statistic could used for User application?
