CIM performance investigation

by Jan Safranek

I tried to find out why our client scripts are so slow and I got quite surprising results. With default lmishell and https:// through loopback, I can get ~5-10 complete requests+responses/sec. Bottleneck are: 1) lmishell - it did some unnecessary queries and it was promptly fixed (http://reviewboard-openlmi.rhcloud.com/r/817/). 2) lmishell - it creates nice Python objects for everything and it takes non-trivial amount of time (and memory), so I did my performance tests with native pywbem. There is not much we can do about it, I can only suggest to use lmishell for tasks, where performance is not that important. 2) pywbem - it opens new TCP connection for each request (rhbz#1004295) and TLS takes some time to establish. 3) sblim-cmpi-base, it's really badly written and forks *a lot* for each request it gets, e.g. they compute amount of swap by calling system("cat /proc/swaps | awk '{print $3;}' | sed 1d"); Results with LMI_Account provider: pywbem + https: 11 requests/sec. pywbem + http: 21 req/sec pywbem + unix socket: 25 req/sec pegasus native C++ library + http: 25 req/sec pegasus native C++ library + unix socket: 33 req/sec Conclusions: 1) HTTPS decreases performance by 25%, I hope it gets much better when rhbz#1004295 is fixed. 2) python decreases performance by another 25% (!), my wild guess is that it's because their XML parser. 3) even with local unix socket and native c++ library, Pegasus takes 30ms to process one request. Note that the tests were done on virtual HW and the amount of requests/sec should be taken as relative measure. Jan
