| 1) Needs more RAM (swap is 1.6GB often times) | |
| 2) Disc is getting too full (82%), causing more SSD garbage collection/moving stuff around on disc. | |
| 3) Not enough cores to handle 100 max_connections -- intrbiz says look at adding cores first as your load average is over core count. | |
| 4) Application processes stealing CPU from postgres | |
| 5) Poorly designed queries -- peerce | |
| Intrbiz says: Log only slow queries so you can get an idea if it is certain queries which are consistently slow. | |
| 6) A possible change is that we are getting a lot of concurrent visits putting strain on the system through analytics caused by bots/spam filters visiting all links at once. We have been seeing that this results in a bunch of INSERT queries getting stuck running for many seconds. Do we need to change the isolation level so these INSERT queries can run smoothly concurrently? |
