Fixing the cache bottleneck
ndobromirov
On any high scale project the drupal community is usually using memcache. The general rule in we follow is: "Add a cache layer and it will be fster!". So what will happen when the cache layer is THE bottle-neck? In this session I will cover the following topics:
- A case study that experienced exactly this issue.
- What were the symptoms that the system was giving out.
- What changes were implemented on the server architecture to mitigate the problems.
- Related Unix network optimizations.
- How Facebook's MCRouter greatly helped us solve the matter.
