Hi,

(CF11.07-ent, IIS8.5)

NUMA and jakarta?
---------------------------
In the application pool that is assigned to my CF application site, there is a setting called "Maximum Worker Processes" and generally this

would be left at 1 (the default). However, this setting supports NUMA and the IIS help on this says: "On a NUMA aware system, if this number is

0, IIS will start as many worker processes as there are NUMA nodes for optimal performance."

Since my system has 2 NUMA nodes, I decided to test this by setting this to 0 on MyTestAppPool. Now in task manager there are two IIS Worker

Process running as MyTestAppPool. Just as one would expect.

Then I add my-CF-test-site.com into MyTestAppPool. (this site uses wsconfig/1/isapi_redirect.dll)

Then I look at isapi_redirect.log and I see an entry I have never seen before:

[warn] init_jk::jk_isapi_plugin.c (3312): Loading different shared memory JK_localhost_1_jakarta/isapi_redirect. Already loaded JK_my-CF-

test-site.com_1_jakarta/isapi_redirect


QUESTION :  Can I use NUMA with CF/jakarta? Should I?

Thanks!

Byron
