I recently launched my project and had around 2000+ users accessing the application within 10 minutes. I have setup memcache to handle the sessions. What happened was that the server went very slow, almost to an unbearable level. I closed down the website because of this to investigate the cause. Is it possible that it is related to memcache connections? A limitation of them?
Note that I am not experienced with memcache so please be thorough with any assitance.
