如何加快批量静音/取消静音用户？

如何解决如何加快批量静音/取消静音用户？

我正在使用 discord.Net 并观察多个语音频道。我跟踪它们是否被机器人静音并存储与此语音通道相关的命令消息 ID。

public sealed class ObservedVoiceChannel
{
    public ulong VoiceChannelId { get; set; }
    public bool IsMuted { get; set; }
    public ulong MessageId { get; set; }
}

我正在使用一个服务作为内存缓存

public sealed class ObservedVoiceChannelsCache : Dictionary<ulong,ObservedVoiceChannel>
{
}

每当我创建命令消息时，我都会添加一个反应作为按钮来静音特定的语音通道。通过切换反应，我可以决定将语音频道静音/取消静音。如果静音状态设置为 true，机器人会将所有用户静音。如果状态设置为 false，该语音频道中的所有用户都将被取消静音。

public sealed class ReactionAddedEventHandler
{
    private const string MutedEmoji = "\uD83D\uDD07";
    private const string UnMutedEmoji = "\uD83D\uDD0A";

    private readonly ObservedVoiceChannelsCache _observedVoiceChannelsCache;

    public ReactionAddedEventHandler(ObservedVoiceChannelsCache observedVoiceChannelsCache)
    {
        _observedVoiceChannelsCache = observedVoiceChannelsCache;
    }

    public async Task OnReactionAdded(
        Cacheable<IUserMessage,ulong> cacheable,ISocketMessageChannel socketMessageChannel,SocketReaction socketReaction)
    {
        string emoteName = socketReaction.Emote.Name;
        bool emoteIsMutedEmoji = emoteName == MutedEmoji;
        bool emoteIsUnMutedEmoji = emoteName == UnMutedEmoji;

        if (emoteIsMutedEmoji || emoteIsUnMutedEmoji)
        {
            ObservedVoiceChannel observedVoiceChannel =
                _observedVoiceChannelsCache.Values.FirstOrDefault(currentObservedVoiceChannel =>
                    currentObservedVoiceChannel.MessageId == socketReaction.MessageId);

            if (observedVoiceChannel != null)
            {
                IMessage message = await socketMessageChannel.GetMessageAsync(cacheable.Id);

                if (message.Reactions[socketReaction.Emote].ReactionCount > 1)
                {
                    SocketGuildChannel socketGuildChannel = socketMessageChannel as SocketGuildChannel;
                    SocketVoiceChannel socketVoiceChannel = socketGuildChannel.Guild.GetVoiceChannel(observedVoiceChannel.VoiceChannelId);
                    IVoiceChannel voiceChannel = socketVoiceChannel as IVoiceChannel;

                    IEnumerable<IGuildUser> voiceChannelUsers = await voiceChannel
                        .GetUsersAsync()
                        .FlattenAsync();

                    Emoji mutedEmoji = new Emoji(MutedEmoji);
                    Emoji unMutedEmoji = new Emoji(UnMutedEmoji);

                    if (observedVoiceChannel.IsMuted && emoteIsUnMutedEmoji)
                    {
                        // switch mode and unmute everyone in that voice channel

                        List<Task> tasks = voiceChannelUsers
                            .Select(voiceChannelUser => voiceChannelUser.ModifyAsync(guildUserProperties => guildUserProperties.Mute = false))
                            .ToList();

                        tasks.Add(message.RemoveAllReactionsForEmoteAsync(unMutedEmoji));
                        tasks.Add(message.AddReactionAsync(mutedEmoji));

                        await Task.WhenAll(tasks);

                        observedVoiceChannel.IsMuted = false;
                    }
                    else if (!observedVoiceChannel.IsMuted && emoteIsMutedEmoji)
                    {
                        // switch mode and mute everyone in that voice channel

                        List<Task> tasks = voiceChannelUsers
                            .Select(voiceChannelUser => voiceChannelUser.ModifyAsync(guildUserProperties => guildUserProperties.Mute = true))
                            .ToList();

                        tasks.Add(message.RemoveAllReactionsForEmoteAsync(mutedEmoji));
                        tasks.Add(message.AddReactionAsync(unMutedEmoji));

                        await Task.WhenAll(tasks);

                        observedVoiceChannel.IsMuted = true;
                    }
                }
            }
        }
    }
}

这个处理程序工作正常，虽然它并不完美。假设观察到的语音通道处于静音状态，返回 false 并且该语音通道中有 8-14 个人。

当对静音表情符号做出反应大约 4 秒时，没有任何反应。之后，每个人都会被机器人静音。我认为这是因为抢占式速率限制。但如果能立即发生就好了……当对大约 12 秒 的取消静音表情做出反应时，什么也没有发生。之后，人们会一步步慢慢静音。这与静音过程不同，因此静音似乎比取消静音更快。

有人知道这个代码是否可以改进或者是否有任何代码导致问题？我想在性能/执行时间方面加快速度。
