free -m on my Linux machine shows that swap memory is almost completely used. However,there is no impact on the system performance. But should i be really bothered? Swap cache also is not used to its fullest? So will this actually impact the performance? Please suggest
total used free shared buffers cached Mem: 32959100 32786348 172752 0 85096 30303388 -/+ buffers/cache: 2397864 30561236 Swap: 4192956 4188456 4500
cat /proc/meminfo|grep Swap
SwapCached: 184012 kB SwapTotal: 4192956 kB SwapFree: 11584 kB
swappiness is 60
Also we can see that lot of free memory under buffers/cache is available .So why is my swap memory used heavily??How will it effect the performance in future?
