sites easily die by apache "ab" pressure testing tool. any solution?
Hi there,
I'm using Nginx+Varnish for web. My current ram is at 70% of the totally ram. Sawp is not using. plenty cache left. However, my site easily dies and get 502 error when I or someone use apache "ab" pressure testing. As soon as get these requests, the memory reaches to full and get 502 error. I used "DoS Deflate" for protection. but it only checks every 60sec. before it checks, the site could have already been down.
I notice the outgoing bandwidth of DO is not enough which is one of the reason causing this problem. I have another 10/year VPS with low setup running a site from other provide takes the same test. it can process and send 30M/s outgoing data which is fine and hardly dies. I'm not saying their are better. I like DO but recently this issue is annoying me.
any solution? thanks in advance.
Cheers
Frank
