We are having two Nginx Server acting as Caching Server behind haproxy
loadbalancer. We are observing a high load on one of the server though we
see equal number of requests coming on the server from application per sec.

We see that out of two server on which load is high i.e around 5 , response
time /latency is high in delivering the content . On same server attached
stats module screenshot shows more number of requests in "Writing" as
comapred to other one on which load is 0.5 and response time /latency is
also low .

Please help what might be causing high load and high number of writing on
one of server.
