The fastest CCcam server: setup and optimization

If you've been reading forums for a week in search of the fastestCCcam server and still see freezes when switching — you're probably looking in the wrong place. Providers' marketing says "1000 locals, 0 hops," yet the channels still lag. The problem is almost never in the advertising promises — it's in the specific config parameters, in the chain of hops, and sometimes in the receiver itself.

Below is a technical investigation without fluff. Specific paths, parameters, and commands.

What "fast CCcam server" really means

ECM response time as the main metric

The speed of card sharing is measured by one number — the time taken to process the ECM request. This is the interval between when the receiver sends the encrypted request and when it receives the control word (CW) back. In the OScam web interface, this can be seen in theReaders andUsers sections — the ECM time column.

The benchmarks are simple: 100–300 ms — excellent, 300–500 ms — acceptable, 500–600 ms — noticeable when switching. Above 600 ms — freezes are guaranteed, especially on channels with frequent key changes. InCCcam you need to look in the log file: lines likeECM time: 245ms appear at debug level 4 and above.

The difference between network speed and decoding speed

Ping to the server and ECM time are different things. A ping of 20 ms to the host does not mean an ECM time of 20 ms. The total delay consists of: network ping to the server, processing time of the request on the server itself, response time of the physical card, and — if a re-sharer is used — network delays at each intermediate node.

In practice, a Nagra or Irdeto card with frequent key changes (every 10–30 seconds) will consistently give a high ECM time, even if the server is in the neighboring rack.

Why "number of cards" does not equal speed

A provider with 2000 "locals" can give an ECM time of 800 ms if its server is overloaded or the cards are behind two or three hops of a re-sharer. A large number of cards reduces the likelihood of channel failure, but does not speed up the decoding process itself. Look for not "how many cards," but what stable ECM time your log shows for a specific reader.

Configuring CCcam.cfg and OScam for minimal delay

Key parameters in /var/etc/CCcam.cfg

The main configCCcam is usually located in/var/etc/CCcam.cfg or/etc/tuxbox/config/CCcam.cfg depending on the Enigma2 distribution. The connection line to the server looks like this:

C: hostname.example.com 12000 username password no { 0:0:2 }

The flagno — do not use the local card for this server.{ 0:0:2 } — CAID:Provider:Hops mask. The hop limit right here already cuts the delay — set it to a maximum of 2.

Parameters that really affect speed:

• CCCAM RECONNSECONDS = 5 — how quickly the client restores the connection after a drop.
• CCCAM KEEPCONNECTED = 1 — keep the connection alive, without reconnections when changing channels.
• CCCAM RECEIVETIMEOUT = 3000 — timeout waiting for a response in ms. Don't set it too low — there will be false timeouts.
• DEBUG LEVEL = 4 — enable detailed logging with ECM time.

Parameters oscam.conf and oscam.server for speed

OScam configs live in/etc/oscam/ or/var/keys/oscam/ — depends on the build. In the section[global] of theoscam.conf key settings for speed:

[global]

lb_mode = 1 — enable loadbalancer. It selects the reader with the lowest historical ECM time.lb_nbest_readers = 2 — send requests to the two best readers simultaneously and take the response that arrives first. This really reduces latency by 50–100 ms on unstable lines.

In the reader section inoscam.server:

[reader]

cccmaxhops = 2 — do not accept cards further than two hops.cccwantemu = 0 — do not request emulators, only physical cards. Without this parameter, the server may push slow emulated cards instead of fast local ones.

Caching: cache-ex and csp

Cache-ex is the most underrated acceleration tool. The idea is simple: if the control word has already been requested by someone and cached on another server, your server gets it instantly from the cache, without waiting for the card's response.

Inoscam.conf to enable cacheex:

[cache]

There are three modes: mode 1 — only receive from cache, mode 2 — receive and send, mode 3 — aggressive push to all pyramids. Start with mode 1 or 2 and connect trusted CSP servers through a separate reader with the protocolcspThe default CSP port is 2500. Incorrect cacheex configuration with unreliable peers can lead to the opposite — garbage CW in the cache and freezes.

Correct values for reconnect and keepalive

Too aggressive reconnect is a common cause of freezes. IfRECONNSECONDS = 1, the client will reconnect at the slightest delay, creating an avalanche of new connections. The optimum is 5–10 seconds.KEEPCONNECTED = 1 is critically important: without it, CCcam drops the connection after each channel, and the next switch waits for a new handshake.

Diagnosing a slow server: where to look for the bottleneck

Reading the OScam and CCcam log

First, enable normal logging. Inoscam.conf:

[global]

In the OScam web interface (usually port 8888), go toReaders → specific reader → ECM History. There you can see each request with the response time. If one reader consistently gives 600+ ms, while others give 150 ms — the problem is specifically in that line.

In the CCcam log, look for lines:

ECM time: 312ms, cache: no, from: myserver

High ECM time only on one reader = a problem in that specific line or card. High on all readers simultaneously = a local problem (network, receiver CPU, DNS).

Measuring ping and packet loss to the source

Standard ping will give a general idea, butmtr (ortraceroute on the receiver via busybox) will show exactly where packets are being lost. Run:

mtr -n --report hostname.example.com

Packet loss of even 1–2% on some intermediate hop means guaranteed periodic freezes, even with an average ECM time of 200 ms. The line may appear fast on average, but unstable with occasional drops is worse than slow but stable.

CPU and I/O on the receiver as a hidden bottleneck

On old Enigma2 boxes with weak processors (Broadcom BCM7362, for example), the decryption process itself adds delay. Check the load:

top

If the load average spikes above 1.0 on a single-threaded CPU when switching channels — the receiver can't keep up. This is especially noticeable on Nagra 3 and Irdeto 2 channels with frequent key changes. Powervu and BISS are easier in this regard — keys change less frequently.

Another hidden bottleneck is a slow SD card or flash memory in the receiver. If OScam writes logs to a slow medium, it adds I/O delay. Move the log to RAM:logfile = /tmp/oscam.log.

Problems on the card provider's side

The server is fast in the morning and slow in the evening from 19:00 to 23:00 — a classic overload of the source during prime time. This is not your problem and not a config issue. Either switch providers or connect an additional reader as a backup.

High ECM time only on HD channels with normal SD — almost always means that HD is going through a separate card or a separate hop with greater delay. Check which reader in the log responds to HD requests, and optimize that one.

How to choose a card source based on technical criteria

What parameters to look at: ECM time, uptime, hops

Before paying for a line, ask for test access for at least 24 hours. Connect the reader in OScam and look not at the average ECM time, but at the spread: if the average is 200 ms, but there are occasional spikes of 1500 ms — this is an unstable line. Such behavior is immediately visible in the log.

Server uptime is more important than peak speed. A line with ECM time of 400 ms and uptime of 99.5% is more practical than a line with 150 ms and daily reboots at 21:00.

Local cards vs resharing and chains

Hop 1 — physical card directly on the provider's server. Hop 2 — card on another server to which your provider is connected. Each additional hop is an additional network round-trip, usually +30–80 ms. Chains of 4–5 hops of resharing give ECM time of 500–700 ms even with excellent ping.

Ask directly: are the cards local or reshared? Hop 1? If the provider avoids answering — it's likely a multi-level resharing.

Stability is more important than peak speed

Competitors usually ignore this point, promoting "minimum ECM time." An unstable line with an average of 150 ms and spikes up to 2000 ms will cause more freezes than a stable line with a constant 350 ms. The receiver waits for a control word when switching — if it arrives after 2 seconds, the screen freezes for 2 seconds. It doesn't matter that "on average everything is fast."

Fine-tuning of networks and protocols

Protocol choice: CCcam vs newcamd vs cccam over csp

Newcamd operates on the principle of "one port — one card profile." The typical port range is 28910–28920. This is convenient for isolating cards but creates overhead with a large number of profiles. CCcam multiplexes everything through one port (usually 12000) with a more complex handshake, but this results in fewer connections.

CSP (CacheEx Sharing Protocol) — a separate story. It operates over UDP and is intended exclusively for sharing cached CW between servers. If you have access to a trusted CSP peer, connect it in OScam as a separate reader — this often provides the fastest CCcam server in real conditions, because popular channels are delivered from the cache in milliseconds.

MTU, TCP, and wired connection

Wi-Fi adds instability — not constant latency, but jitter. A ping of 5 ms over Wi-Fi with a jitter of 30 ms is worse than wired Ethernet with a ping of 8 ms and a jitter of 1 ms. For card sharing, stability is critical, not peak channel speed.

The default MTU of 1500 bytes is usually fine. If the provider uses PPPoE (DSL), the effective MTU drops to 1492. MTU mismatch leads to packet fragmentation and increased latency. It's easy to check:

ping -M do -s 1472 hostname.example.com

If you seeFrag needed — lower the MTU on the receiver's interface.

Reducing the number of hops in the chain

The most straightforward way to speed up the fastest CCcam server in practice is to cut long resharing chains with the parametercccmaxhops inoscam.server. Set the value to a maximum of 2–3:

cccmaxhops = 2

OScam will stop accepting cards beyond the second hop. Yes, the number of available cards will decrease. However, those that remain will respond quickly. Better to have fewer cards with ECM time of 200 ms than a hundred cards with ECM time of 800 ms.

The same thing in CCcam is done through a mask in the connection string — the third number in curly braces:{ 0:0:2 }.
