Hi,
We have a rails app which is essentially a web UI to a unix
filesystem, and which has been performing rather slowly. I've been
looking at rewriting it in merb, so I did a quick spike where I ported
over all the rails code necessary to log in as a user, and generate
the same file list page that rails was serving up. However, the
numbers appear quite bad (twice as slow as rails, for a naive
benchmark), leading me to believe that I'm doing something wrong. I'll
try to get permission to post some code, but on general principles are
there any pitfalls to look for when converting rails code to merb?
Also, I'm trying to do some sort of rough client-side benchmarking
using the following code - is there anything obviously wrong with it?
I'm getting numbers of over 10 seconds per page load when I have 50
users repeatedly requesting a dynamic page in a loop:
client = HTTPAccess2::Client.new
client.set_cookie_store("cookie.dat")
client.post(url, {:user_login => login, :user_password => pwd})
client_time = []
all_client_avg = []
all_server_avg = []
$total_client_avg = []
$total_server_avg = []
num_iterations.times do |i|
folders =
YAML.load(client.get_content("#{url}/folder/all_user_folders"))
folders.each do |folder|
client_time << Benchmark.realtime do
response_size =
client.post("#{url}/resources/set_current_folder",
{:folder => $folder}).content.length
end
end
client_avg = (client_time.inject(0) {|sum, element| sum + element}) /
client_time.length
end
I'm rather new to both web development and benchmarking, so please
feel free to talk to me as if I were an idiot :)
