Fragment interface on Intel
Hi It seem that the fragment interface on certain plugins exceeds the amount of fragment operations possible on Intel GMA cards. This only occurs with the "water" and "blur" plugins. the plugins activate OK and do not report a missing GL_ARB_fragment_program in the server extensions. Waves appear when I use...

Rails 2.3 memcache performance drop
...10x longer than before. Here are some example numbers from my development log (below), with memcache running locally. We see similar scale of performance drop in production as well - average memcache call before 2ms, now 20ms. It adds up to a significant hit. Before Rails 2.3 upgrade: Cached fragment hit: views/homepage_recent_blog_posts (0.00043) Cached fragment hit: views/homepage_active_threads (0.00033) Cached fragment hit: views/homepage_weekly_feature (0.00029) Cached fragment hit: views/homepage_recent_approved_items (0.00036) Cached fragment hit: views/homepage_popular_items (0.00037) C...

[PATCH net] xen-netback: fix fragment detection in checksum setup
The code to detect fragments in checksum_setup() was missing for IPv4 and too eager for IPv6. (It transpires that Windows seems to send IPv6 packets with a fragment header even if they are not a fragment - i.e. offset is zero, and M bit is not set).

New video card; wine freezing
Hello, I want to play Eve Online in Wine. It was working (mostly) on my old card, a GTX 280, using the nvidia driver. It was the 3rd card I've had from Nvidia in a row with manufacturing defects, so I bought a Radeon 6870, which is working good except with Wine. I am using fglrx, and have a dual head setup using xrandr. When I log in, I get to the screen where it is entering the game after I

File fragmentation
...nd-line option. I've noticed there is some penalty for very large files (35GB-50GB). The penalty is relatively small based on my 'intuitive' measurements.read me watching without running a real timer. The difference is very small compared to what happens after a few weeks without the fragmentation patch. Our SAN was becoming so fragmented that we were only getting 10% of normal throughput. Since we've applied this patch our SAN is continuously getting maximum throughput. Benchmarks are numbers such as 10MB/sec throughput due to fragmentation versus 90MB-150MB without fragmentatio...

Fragmented DWARF
...resented a lightning talk on an approach to reduce the amount of dead debug data left in an executable following operations such as --gc-sections and duplicate COMDAT removal. In that presentation, I presented some figures based on linking a game that had been built by our downstream clang port and fragmented using the described approach. Since recording the presentation, I ran the same experiment on a clang package (this time built with a GCC version). The comparable figures are below: Link-time speed (s): +--------------------+-------+---------------+------+------+------+------+------+ | Package va...

[Bug 48] conntrack breaks udp path mtu discovery
https://bugzilla.netfilter.org/cgi-bin/bugzilla/show_bug.cgi?id=48 ------- Additional Comments From tatonet@tiscali.it 2004-02-25 15:05 ------- I know that this is an old bug report, but it's still opened... If we save the size of each single fragment we have to face another problem: how should we re-fragment the packet if original fragments were partially or totally overlapped? Another approach could be the following: if the DF flag is set in the fragments of a packet, the maximum length fragment determines the fate of the whole packet d...

zfs defragmentation via resilvering?
Hello all, I understand that relatively high fragmentation is inherent to ZFS due to its COW and possible intermixing of metadata and data blocks (of which metadata path blocks are likely to expire and get freed relatively quickly). I believe it was sometimes implied on this list that such fragmentation for "static" data can be currently...
