But as > an observation when i had less than 2000 VLAN's this was not the case > it is used to fluctuate between 10-40-100 but predominently 100%. Hmmmm... I once did some testing on performance of directories in the ext2 filesystem. I found that directory operations - list, add a file, remove a file, etc. were frisky up until about 1000 entries. By 2000 entries there was a perceptible slowdown. With 4000 entries in a directory, it took over a day just to remove all the files. My conclusion was that the directory operations were iterating the entire directory list for each operation, leading to exponential performance degradation. I saw the same problem adding routes, with the same thresholds. If this is your issue, you will have problems no matter what, but heavy caching should help matters a little. To test this, do an ls in the directory that holds all the vlans.
