Tunning HAProxy performance by use multiple processors and config caching for frontend
I/Config multithreading by use multiple processor for frontend:
#Define cpu-map in global:
global
nbproc 4 #generate 4 process when haproxy started
cpu-map 1 0
cpu-map 2 1
cpu-map 3 2
cpu-map 4 3
frontend web_in
bind-process 1 2 3 4
II/Use small cache for user’s file access:
1/Define acl for using/store file to cache named image by URL:
frontend web_in
http-request set-var(txn.path) path
acl is_image if path -i -m sub images # Define acl name is_image by URL
http-request cache-use image if is_image #Using cache store named image
http-request cache-store image if is_image #Store files request to cache store named image
2/Define cache store for frontend using/storing:
cache image
max-age 210 # in seconds
total-max-size 3 # allow cache total maximum 3MB for a same host and same URI request
global
tune.bufsize 32768 # not store file to cache store if larger than 32KB
