First of all, thanks for great module.

I am using "Cache once for everything" option for all the blocks. I turned on "Display Page Timer" from Devel. My page load times have gone up instead of lesser page times. Is there any other configuration required?

I switched to "Per Page", but still page load times are higher without module installed.

Thanks

I think user 1 doesn't get block caching. Try it when the UID != 1.

Using an account with a UID!= 1:

Using apachebench locally, 10 concurrent, 1000 requests (ab -n 100 -c 10):

before blockcache_alter:
Requests per second: 19.96 [#/sec] (mean)
Requests per second: 19.88 [#/sec] (mean)

after blockcache_alter:
Requests per second: 19.74 [#/sec] (mean)
Requests per second: 19.65 [#/sec] (mean)

Slight slowdown in performance. According to Xhprof blocks are taking over 50% of our render times.

I did this to enable caching:
UPDATE block set cache=8;
DELETE FROM blockcache_alter;
INSERT INTO blockcache_alter SELECT bid, module, delta, cache FROM block;

Are you using context ? In this case, see this bug #1251240: Context block reaction lists blocks without calling hook_block_info_alter(). which proposed a patch and this module : https://drupal.org/project/context_blockcache_alter which embed this patch in a proper module.

Same problem here with no context module enabled.

Getting same result as the rest, getting minor reduced performance, block are not cached AFAICT.

Tested with
- UID != 1
- no context
- core/module block
- custom block

Issue summary: View changes

I assume you are using a node_grants using module. You will indeed need the patch from #1562700: Getting back expiration feature into D7 version for block.module.

Leaving open as I might have something better soon :-D.

Title: No Performance achieved. » [Solutions inside] No Performance achieved.

You can use the render_cache module version 7.x-2.x together with block cache alter by enabling render_cache_block core's block cache, which is taken over by render cache.

That makes it possible to use without the node grants patch.

You can also set:

drush vset render_cache_debug 1

to see lots more information about the blocks being cached.

Also there is now the core variable to enable block cache regardless of node_grants setting: block_cache_bypass_node_grants

Thanks,

Fabian
