Hey guys,
I am sorta informally looking at the performance of OpenEJB. Now I am
certainly not trying to open a can of worms here. :-) An idea that I
am currently playing with is to modify the client so that it can re-use
an existing open socket connection to the server rather then doing
open-write-read-close and at the same time, the server will loop and
keep reading requests from the same socket.
My first thought was to enhance the OEJP to support "headers" like HTTP
does and then use the "keepalive" idea. I bumped up the OEJP version to
2.1 so that the client/server would know to check for the existance of
headers in the request/response. The marshalled headers would be in the
format of:
Existing structure: [OEJP/2.0][request-id][request-data]
New structure:
[OEJP/2.1][#-of-headers][headers][request-id][request-data] where
headers is [len][name-data][len][value-data]
This saved, combined with socket pooling, approx. 34%
My second thought was to avoid the NVP headers and use a byte array of
bit flags, the new format is:
[OEJP/2.1][byte-of-flags][request-id][request-data]
This is 27% faster then my first thought.
I like to carry this forward a little more, but I would like to peoples
thoughts on this first.
Thanks
Mark
